Isesengura ku mpinduka z'uburyo bwo gukoresha PE mu gihe kiri imbere.
Muri iki gihe, ingano ya polyethylene ikoreshwa mu gihugu cyanjye ni nini, kandi uburyo bwo gushyira mu byiciro ubwoko bw'ibicuruzwa bya pulasitiki mu byiciro biragoye kandi ahanini bigurishwa mu buryo butaziguye n'inganda zikora ibikoresho bya pulasitiki. Ni igice cy'ibicuruzwa bya pulasitiki mu ruhererekane rw'inganda za éthylene. Hamwe n'ingaruka z'ubwinshi bw'ibicuruzwa bikoreshwa mu gihugu mu karere, icyuho cy'ibicuruzwa n'ibikenewe mu karere ntikiringaniye. Bitewe no kwaguka k'ubushobozi bw'umusaruro w'ibigo bitunganya polymere byo mu gihugu cyanjye mu myaka yashize, uruhande rw'ibicuruzwa rwariyongereye cyane. Muri icyo gihe, bitewe n'iterambere rihoraho ry'umusaruro n'imibereho y'abaturage, icyifuzo cyabyo cyariyongereye cyane mu myaka ya vuba aha. Ariko, kuva mu gice cya kabiri cya 202... -
Ni ubuhe bwoko butandukanye bwa polypropylene?
Hari ubwoko bubiri bw'ingenzi bwa polypropylene buboneka: homopolymers na copolymers. Copolymers zigabanyijemo ibice bibiri: block copolymers na random copolymers. Buri cyiciro gihuye neza n'ibindi bikorwa kurusha ibindi. Polypropylene ikunze kwitwa "icyuma" cy'inganda za pulasitiki bitewe n'uburyo butandukanye ishobora guhindurwamo cyangwa guhindurwa kugira ngo igere ku ntego runaka. Ibi bikunze kugerwaho binyuze mu kuyishyiramo inyongera zidasanzwe cyangwa mu kuyikora mu buryo bwihariye. Uku guhinduka ni ingenzi. Homopolymer polypropylene ni urwego rusange rw'intego. Ushobora gutekereza ibi nk'uko ibintu bya polypropylene bimeze mbere. Block copolymer polypropylene ifite ibice bya co-monomer bitondetse mu bice (ni ukuvuga, mu buryo busanzwe) kandi birimo... -
Ni ibihe biranga Polyvinyl Chloride (PVC)?
Zimwe mu ngaruka zikomeye za Polyvinyl Chloride (PVC) ni: Ubucucike: PVC ni nini cyane ugereranije na pulasitiki nyinshi (uburemere bwihariye buri hafi ya 1.4) Ubukungu: PVC iraboneka byoroshye kandi ihendutse. Ubukomere: PVC ikomeye irakomeye kubera ubukomere n'ubudahangarwa. Ingufu: PVC ikomeye ifite imbaraga nziza zo gukurura. Polyvinyl Chloride ni ibikoresho bya "thermoplastic" (bitandukanye na "thermoset"), bifitanye isano n'uburyo pulasitiki ikira ubushyuhe. Ibikoresho bya thermoplastic biba amazi aho bishongesha (urugero rwa PVC ruri hagati ya dogere selisiyusi 100 zo hasi cyane n'agaciro ko hejuru nka dogere selisiyusi 260 bitewe n'inyongera). Ikintu cy'ingenzi kiranga thermoplastic ni uko ishobora gushyushya kugeza aho ishongesha, ikonjeshwa, kandi ikongera gushyuha ... -
Soda ya caustic ni iki?
Mu rugendo rusanzwe rwo kujya muri supermarket, abaguzi bashobora kugura isabune, bakagura icupa rya aspirine bakareba ingingo ziheruka ku binyamakuru n'amagazeti. Urebye bwa mbere, bishobora gusa nkaho ibi bintu bidahuriyeho byinshi. Ariko, kuri buri kimwe muri byo, soda ya caustic igira uruhare runini mu rutonde rw'ibikoreshwa cyangwa mu mikorere yabyo. Soda ya caustic ni iki? Soda ya caustic ni chemical compound sodium hydroxide (NaOH). Iyi composite ni alkali - ubwoko bw'ishingiro bushobora kwangiza aside kandi bugashonga mu mazi. Muri iki gihe soda ya caustic ishobora gukorwa mu buryo bw'udupira, uduce duto, ifu, ibisubizo n'ibindi. Soda ya caustic ikoreshwa iki? Soda ya caustic yabaye ikintu gisanzwe mu gukora ibintu byinshi bya buri munsi. Izwi cyane nka lye, yakoreshejwe mu ... -
Kuki Polypropylene ikoreshwa kenshi?
Polypropylene ikoreshwa mu bikorwa byo mu ngo no mu nganda. Imiterere yayo yihariye n'ubushobozi bwayo bwo guhuza n'uburyo butandukanye bwo gukora bituma igaragara nk'ibikoresho by'agaciro gakomeye mu bikorwa bitandukanye. Ikindi kintu cy'ingenzi kiranga polypropylene ni ubushobozi bwayo bwo gukora nk'ibikoresho bya pulasitiki ndetse n'ibikomoka kuri fibre (nk'udukapu twamamaza dutangwa mu birori, amarushanwa, n'ibindi). Ubushobozi bwihariye bwa polypropylene bwo gukorwa hakoreshejwe uburyo butandukanye no mu bikorwa bitandukanye byatumye itangira guhangana n'ibikoresho byinshi bishaje, cyane cyane mu nganda zipakira, fibre, n'izikora inshinge. Iterambere ryayo ryakomeje mu myaka yashize kandi rikomeje kuba umukinnyi ukomeye mu nganda za pulasitiki ku isi. Muri Creative Mechanisms, dufite... -
Chemdo yatumiwe kwitabira inama yateguwe ku bufatanye na Google na Global Search.
Amakuru agaragaza ko mu buryo bw'ubucuruzi bwa elegitoroniki mu Bushinwa mu 2021, ibikorwa bya B2B byambukiranya imipaka byageze hafi kuri 80%. Muri 2022, ibihugu bizinjira mu cyiciro gishya cyo kuvugurura icyorezo. Kugira ngo bihangane n'ingaruka z'icyorezo, kongera gukora imirimo no gukora byahindutse ijambo rikunze gukoreshwa cyane ku bigo by'imbere mu gihugu n'ibyo mu mahanga bitumiza n'ibyohereza mu mahanga. Uretse icyorezo, ibintu nk'izamuka ry'ibiciro by'ibikoresho fatizo biterwa n'ihungabana rya politiki mu gihugu, kwiyongera kw'imizigo yo mu mazi, guhagarika ibicuruzwa biva mu byambu, no kugabanuka kw'agaciro k'amafaranga ajyanye nabyo guterwa n'izamuka ry'inyungu ku madolari ya Amerika byose bigira ingaruka ku bucuruzi mpuzamahanga bwose. Muri iki gihe kigoye, Google n'umufatanyabikorwa wayo mu Bushinwa, Global Sou, bakoze inama yihariye... -
Uduce twa PVC ni iki?
PVC ni imwe mu pulasitiki zikoreshwa cyane mu nganda. Plasticol, ikigo cy’Abataliyani giherereye hafi ya Varese kimaze imyaka irenga 50 gikora uduce twa PVC kandi ubunararibonye bwakusanyijwe mu myaka yashize bwatumye ikigo kirushaho kugira ubumenyi bwimbitse ku buryo ubu dushobora kuyikoresha kugira ngo duhuze ibyifuzo by’abakiriya bose batanga ibikoresho bishya kandi byizewe. Kuba PVC ikoreshwa cyane mu gukora ibintu bitandukanye bigaragaza uburyo imiterere yayo y’ibanze ari ingirakamaro cyane kandi yihariye. Reka dutangire tuvuga ku gukomera kwa PVC: ibikoresho birakomeye cyane iyo ari byo byonyine ariko birahinduka iyo bivanze n’ibindi bintu. Iyi miterere yihariye ituma PVC ikwiriye gukora ibicuruzwa bikoreshwa mu nzego zitandukanye, kuva ku nyubako imwe kugeza kuri... -
Indabyo zishobora kwangirika zishobora guhindura urwego rw'ubwiza.
Ubuzima bwuzuyemo ibipfunyika birabagirana, amacupa yo kwisiga, amasahani y'imbuto n'ibindi, ariko byinshi muri byo bikozwe mu bikoresho by'uburozi kandi bidahoraho bigira uruhare mu kwanduzanya kwa pulasitiki. Vuba aha, abashakashatsi bo muri Kaminuza ya Cambridge mu Bwongereza babonye uburyo bwo gukora ubwiza burambye, budahumanya kandi bushobora kubora buturutse kuri cellulose, inkingi ikomeye y'inkuta z'uturemangingo tw'ibimera, imbuto n'imboga. Inyandiko zijyanye nazo zasohotse mu kinyamakuru Nature Materials on the 11th. Iyi ubwiza ikoresha amabara y'imiterere kugira ngo ihindure urumuri kugira ngo itange amabara meza. Urugero, muri kamere, urumuri rw'amababa y'ibinyugunyugu n'ubwoya bw'ingwe ni ibihangano by'amabara y'imiterere, bitazashira nyuma y'ikinyejana. Hakoreshejwe uburyo bwo kwihuza, cellulose ishobora gukora ... -
Resin ya Polyvinyl chloride (PVC) paste ni iki?
Resin ya polyvinyl chloride (PVC) paste, nk'uko izina ribisobanura, ni uko iyi resin ikoreshwa cyane mu buryo bwa paste. Abantu bakunze gukoresha ubu bwoko bwa paste nka plastisol, ikaba ari ubwoko bwihariye bw'amazi bwa pulasitiki ya PVC mu gihe itaratunganywa. . Paste resins ikunze gutegurwa hakoreshejwe emulsion na micro-suspension methods. Paste resins ya polyvinyl chloride paste ifite ingano nto y'uduce, kandi imiterere yayo isa na talc, idahinduka.

Mu gukora paste, hongerwamo ibintu bitandukanye byuzuza, bigabanya ubushyuhe, ibitera imbaraga zo gushyuha, ibintu bitera imbaraga zo gufuro n'ibitera imbaraga zo guhagarara bitewe n'uko ... -
Filime za PP ni iki?
IMITERERE Polypropylene cyangwa PP ni thermoplastic ihendutse kandi isobanutse neza, irabagirana cyane kandi ifite imbaraga zo gukurura. Ifite aho ishongesha cyane kurusha PE, bituma ikoreshwa mu buryo busaba koroshya ubushyuhe mu bushyuhe bwinshi. Ifite kandi ibara ry'umukara rito kandi irabagirana cyane. Muri rusange, imiterere ya PP yo kuziba ubushyuhe ntabwo ari myiza nk'iya LDPE. LDPE kandi ifite imbaraga zo gushwanyagurika neza no kudakora neza mu bushyuhe. PP ishobora gukoreshwa mu byuma bigatuma habaho imiterere myiza yo kubuza gazi gukoreshwa mu buryo busaba imbaraga nyinshi aho igihe kirekire cyo kubika ibicuruzwa ari ngombwa. Filimi za PP zikwiriye cyane mu nganda, abaguzi, n'imodoka. PP ishobora kongera gukoreshwa mu buryo bwuzuye kandi ishobora kongera gukoreshwa mu bindi bicuruzwa byinshi mu buryo butandukanye. Ariko, nta... -
PVC ni iki?
Imvange za PVC zishingiye ku ruvange rwa PVC polymer RESIN n'inyongera zitanga imvange ikenewe kugira ngo ikoreshwe burundu (Imiyoboro cyangwa Imvange Zihamye cyangwa Imvange Zihindagurika cyangwa Amashuka). Imvange ikorwa no kuvanga neza ibintu, hanyuma bigahinduka ikintu "gikozwemo gel" bitewe n'ubushyuhe n'imbaraga zo gukata. Bitewe n'ubwoko bwa PVC n'inyongera, imvange mbere yo gukaraba ishobora kuba ifu itemba (izwi nk'uruvange rwumye) cyangwa amazi mu buryo bwa paste cyangwa umuti.
