Ni iyihe miti Ubushinwa bwohereje muri Tayilande?
Iterambere ry'isoko ry'ibinyabutabire ryo muri Aziya y'Amajyepfo y'Uburasirazuba rishingiye ku itsinda rinini ry'abaguzi, abakozi bahendutse, na politiki zidafite ishingiro. Bamwe mu bantu bakora muri urwo rwego bavuga ko imiterere y'isoko ry'ibinyabutabire muri Aziya y'Amajyepfo y'Uburasirazuba isa cyane n'iy'Ubushinwa mu myaka ya 1990. Bitewe n'iterambere ryihuse ry'inganda z'ibinyabutabire zo mu Bushinwa, icyerekezo cy'iterambere ry'isoko ry'ibinyabutabire ryo muri Aziya y'Amajyepfo cyarushijeho kugaragara neza. Rero, hari ibigo byinshi bireba imbere byagura cyane inganda z'ibinyabutabire zo muri Aziya y'Amajyepfo y'Uburasirazuba, nka epoxy propane inganda z'inganda n'uruhererekane rw'inganda za propylene, no kongera ishoramari ryabyo ku isoko rya Vietnam.

Ubwiyongere bugaragara bw'umusaruro w'amashanyarazi menshi mu gihugu no kugabanuka kw'itandukaniro ry'ibiciro ku murongo
Kuva mu 2020, inganda za polyethylene zo mu ngo zinjiye mu cyiciro rusange cy’ikwirakwizwa ry’ingufu, kandi ubushobozi bw’umusaruro w’ingufu zo mu ngo ziyongereye cyane buri mwaka, aho impuzandengo y’izamuka ry’ingufu zo mu ngo zirenga 10%. Umusaruro wa polyethylene ikorerwa mu ngo wiyongereye cyane, hamwe n’ihinduka rikomeye ry’ibicuruzwa ndetse n’irushanwa rikomeye ku isoko rya polyethylene. Nubwo icyifuzo cya polyethylene nacyo cyagaragaje icyerekezo cy’izamuka ry’ingufu mu myaka ya vuba aha, ukwiyongera kw’ibikenewe ntikwihutishije nk’uko umuvuduko w’izamuka ry’ibicuruzwa byatanzwe. Kuva mu 2017 kugeza mu 2020, ubushobozi bushya bwo gukora polyethylene yo mu ngo bwibanze cyane ku bwoko bufite voltage nke n’ubugari, kandi nta bikoresho bifite voltage nyinshi byashyizwe mu bikorwa mu Bushinwa, bigatuma habaho umusaruro mwiza ku isoko rifite voltage nyinshi.

Filimi yo gupfunyikaho ya Polypropylene ishingiye ku ruhande rumwe n'urundi ruhande ni iki?
Filimi ya polypropylene ishingiye ku murongo wa biaxial (BOPP) ni ubwoko bwa filime yo gupfunyika ikoresha uburyo bworoshye. Filimi yo gupfunyika ishingiye ku murongo wa biaxial iramburirwa mu mashini no mu cyerekezo cyo kuzenguruka. Ibi bituma habaho icyerekezo cy’uruhererekane rw’ibice byombi. Ubu bwoko bwa filime yo gupfunyika ikoreshwa mu buryo bworoshye ikorwa binyuze mu buryo bwo gukora umuyoboro. Umubyimba wa filime umeze nk'umuyoboro urashyuha ugashyuha kugeza aho woroshye (ibi bitandukanye n'aho ushongesha) kandi uramburirwa n'imashini.

Kuzamuka k'ubusabe bwa PVC ku isi biterwa n'Ubushinwa.
Mu mwaka wa 2023, bitewe n’igabanuka ry’ibiciro mu turere dutandukanye, isoko rya polyvinyl chloride (PVC) ku isi riracyafite ibibazo. Mu gice kinini cya 2022, ibiciro bya PVC muri Aziya na Leta Zunze Ubumwe za Amerika byagaragaje igabanuka rikomeye ndetse bigabanuka mbere yo kwinjira mu 2023. Mu mwaka wa 2023, mu turere dutandukanye, nyuma y’uko Ubushinwa buvuguruye politiki yabwo yo gukumira no kurwanya icyorezo, isoko ryiteze ko rizasubiza; Leta Zunze Ubumwe za Amerika zishobora kongera inyungu mu rwego rwo kurwanya izamuka ry’ibiciro no kugabanya ikiguzi cya PVC mu gihugu muri Amerika. Aziya, iyobowe n’Ubushinwa, na Leta Zunze Ubumwe za Amerika byaguze ibicuruzwa bya PVC byoherezwa mu mahanga mu gihe hari ikiguzi gito ku isi. Ku bijyanye n’Uburayi, akarere kazakomeza guhura n’ikibazo cy’ibiciro by’ingufu nyinshi n’ihungabana ry’ibiciro, kandi birashoboka ko nta kuzamuka ku buryo burambye kw’inyungu z’inganda. ...
