Xitoy va global miqyosda PVX sig'imi haqida ma'lumot
2020 yilda statistikaga ko'ra, global PVX umumiy ishlab chiqarish hajmi 62 million tonnaga etdi va umumiy ishlab chiqarish 54 million tonnaga etdi. All the reduction in output means that the production capacity did not run 100%. Tabiiy ofatlar, mahalliy siyosati va boshqa omillar tufayli ishlab chiqarish quvvatiga qaraganda kamroq bo'lishi kerak. Evropa va Yaponiyada PVXning yuqori ishlab chiqarish qiymati tufayli PVX ishlab chiqarish quvvati asosan Shimoli-sharqiy Osiyoda joylashgan, Xitoyning global ishlab chiqarish quvvatining yarmiga ega. Shamol ma'lumotlariga ko'ra, 2020 yil, Xitoy, AQSh va Yaponiyada dunyoda muhim PVX ishlab chiqarish maydonlari, shuningdek mos ravishda 42%, 12% va 4%. 2020 yilda PVC Global Eng yaxshi uchta korxona ... -
PVX qatronlari kelajakdagi tendentsiyasi
PVX - bu qurilish materiallarida keng ishlatiladigan plastmassa. Shuning uchun kelajakda u uzoq vaqt almashtirilmaydi va kelajakda kam rivojlangan sohalarda katta imkoniyatlarga ega bo'ladi. Barchamizga ma'lumki, PVX ishlab chiqarishning ikki usuli bor, biri xalqaro umumiy etilen usuli, ikkinchisi Xitoyda noyob kaltsiy karbid usuli. Etilen usulining manbalari asosan neft, kaltsiy karbid usuli, asosan ko'mir, ohaktosh va tuz. Ushbu resurslar asosan Xitoyda jamlangan. Uzoq vaqt davomida Xitoyning PVX kaltsiy karbid usuli mutlaq etakchi mavqega ega. Ayniqsa 2008 yildan 2014 yilgacha Xitoyning PVX ishlab chiqarish hajmi tobora ko'payib bormoqda, ammo u ham olib keldi ... -
PVX REVIN nima?
Polyvinyl chloride (PVC) is a polymer polymerized by vinyl chloride monomer (VCM) in peroxide, azo compound and other initiators or according to the free radical polymerization mechanism under the action of light and heat. Vinil xlorid gomopolimeri va vinilxlorid kopolimeri birgalikda vinilxlorid qatroni deb ataladi. PVX dunyodagi eng katta umumiy maqsadli plastmassa bo'lib, keng qo'llaniladi. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging film, bottles, foaming materials, sealing materials, fibers and so on. Turli dastur doirasiga ko'ra, PVXni ikkiga bo'lish mumkin: PVX rezin, yuqori daraja pvc yuqori darajadagi polimeratsiya qilish puc rezin va ... -

Chemdodagi xodimlar epidemiyaga qarshi birgalikda kurashmoqda
2022 yil mart oyida Shanxay shaharni yopish va nazorat qilishni amalga oshirdi va "tozalash rejasini" amalga oshirishga tayyorlandi. Hozir taxminan aprel oyining o'rtalarida, biz faqat uyda derazadan tashqaridagi go'zal manzarani tomosha qilishimiz mumkin. Shanxayda epidemiya tendentsiyasi tobora kuchayib borishini hech kim kutmagan edi, ammo bu epidemiya ostida bahorda butun Chemdoning ishtiyoqini hech qachon to'xtata olmaydi. Chemdo kompaniyasining butun jamoasi "uyda ishlash" ni amalga oshiradi. Barcha bo'limlar birgalikda ishlaydi va to'liq hamkorlik qiladi. Ish bilan bog'lanish va topshirish video ko'rinishida onlayn tarzda amalga oshiriladi. Videodagi yuzlarimiz doim bo'yanishsiz bo'lsa-da, ishga jiddiy munosabat ekranni to'ldirib yuboradi.

2021 yilda Xitoyning polilaktik kislota (PLA) sanoat zanjiri
1. Sanoat zanjirining umumiy ko'rinishi: Polilaktik kislotaning to'liq nomi polilaktik kislota yoki polilaktik kislotadir. Bu monomer sifatida sut kislotasi yoki sut kislotasi dimer laktidi bilan polimerizatsiya natijasida olingan yuqori molekulyar polyester materialdir. U sintetik yuqori molekulyar materialga tegishli bo'lib, biologik asos va parchalanish xususiyatlariga ega. At present, polylactic acid is a biodegradable plastic with the most mature industrialization, the largest output and the most widely used in the world. Polikonact kislotasi sanoatining yuqori qismida makkajo'xori, shakar lavlagi va boshqalar kabi asosiy xom ashyoning barcha turlari, masalan, polial kislotani tayyorlash, asosan polistream. -
Biogleelda polimer pba katta vaqtga tegmoqda
Zo'r polimer - fizik xususiyatlar va atrof-muhitning ta'siri yo'q -, ammo poliborlena MiePate Comeftallate (Pbat) ko'pchiliklarga qaraganda yaqinroq keladi. Sintetik polimerlarning ishlab chiqaruvchilari o'nlab yillar davomida o'z mahsulotlarini poligonlar va okeanlarda tugashini to'xtata olmadilar va endi ular javobgarlikni o'z zimmalariga olishlari mumkin. Ko'pchilik tanqidchilarni jalb qilish uchun ishlov berish uchun harakat qilmoqdalar. Other firms are trying to tackle the waste problem by investing in biodegradable biobased plastics such as polylactic acid (PLA) and polyhydroxyalkanoate (PHA), hoping natural degradation will mitigate at least some of the waste. Ammo qayta ishlash va biopinsillilar ham to'siqlarga duch kelishadi. Yiliga qaramay ... -
