Mahsulot ta'rif
Product Introduction
The amorphous silica made by German Netzsch equipment is a high-performance additive, serving as a matting, anti-blocking and antiblocking agent. It can fully substitute similar products like AB905 from American PQ Company and Sylobloc series from Grace. Widely applied in plastic masterbatches and films such as polyolefin and polyester (PET), as well as in combinations with PP, PE and PVC. Its porous nature effectively reduces adhesion and molecular cohesion, minimizing the adhesion tendency to ensure efficient production and use.
Product Features
- Superior Anti-blocking: Effectively resolves material adhesion, guaranteeing product quality.
- Reduces Terminal Yellowing: Significantly mitigates "terminal yellowing", maintaining product appearance.
- High Dispersibility: Evenly disperses in material systems, ensuring stable performance.
- High Transparency: Has minimal impact on film transparency and haze.
Working Principle
Polymer macromolecules' strong intermolecular forces cause film layer adhesion, leading to processing and handling issues. The inorganic silica antiblocking agent forms a microscopic "rough" structure on the polymer film surface, disrupting these forces, reducing adhesion and facilitating layer separation for better film performance and usability.

Mahsulot tafsilotlari
Ochilish agenti kremniy dioksidiga kirish
Mahsulotning kimyoviy xossalari barqaror, bu plyonkaning yopishqoqligini samarali ravishda oldini oladi, ishqalanish koeffitsientini kamaytiradi, plyonkaning o'rashini silliq qiladi, ajinlarni kamaytiradi, plyonkani ikkilamchi kesish yoki ochishni osonlashtiradi va moylash materiallari yoki antistatik moddalarning bir xil migratsiyasini osonlashtiradi.
Funktsionallik nuqtai nazaridan, ochuvchi vosita silikasining asosiy vazifasi materialning yopishishini oldini olishdir. Plastmassa plyonka ishlab chiqarish jarayonida, masalan, polietilen va polipropilen plyonkalarga kremniy dioksiddan tayyorlangan ochiladigan masterbatch qo'shilishi, plyonka yuzasida kichik o'simtalar hosil qilishi, plyonkalar orasidagi aloqa maydonini kamaytirishi va shu bilan plyonkalar orasidagi ishqalanishni kamaytirishi mumkin, bu esa plyonkani yopishmasdan ochish uchun silliqroq qiladi.
Mahsulotimiz yaxshi dispersiyaga ega va ko'p kristalli nuqtalarni hosil qilmaydi. Zarrachalar hajmi o'rtacha va teng taqsimlanadi va filtr ekranini blokirovka qilish oson emas. Sinishi ko'rsatkichi qatronga o'xshaydi, bu plyonkaning shaffofligiga ta'sirini kamaytiradi, uskunaning eskirishini kamaytiradi va tabiiy va bir xil rangga ega. Filmning sirtini chizmaydi va qadoqlash effektiga ta'sir qilmaydi.
Muayyan ilovalar uchun zarracha hajmi 3-8 m m bo'lgan sintetik silika ochuvchi vositalar odatda kukun shaklida qo'llaniladi. Ularni eritish va 5-10% yuqori konsentratsiyali masterbatchga plastiklashtirish uchun avval ularni ikki vintli ekstruder orqali ma'lum miqdorda tashuvchi qatronlar bilan aralashtirish kerak. Keyin ular plyonka mahsulotiga ma'lum nisbatda qo'shilishi va kompozit masterbatch hosil qilish uchun boshqa qo'shimchalar bilan aralashtirilishi mumkin. Qatronlar ishlab chiqaruvchilari uchun quyi oqim plyonka ishlab chiqaruvchilari foydalanishi uchun maxsus materiallarni tayyorlash uchun polimer ishlab chiqarish jarayoniga oz miqdorda 0,1% dan 1% gacha qo'shiladi. Sanoatda keng tarqalgan navlar uchun javob beradi va qo'shilgan ochilish agenti miqdori har xil turdagi filmlarga qarab o'zgaradi.
Qo'llash sohalari: Ikki tomonlama yo'naltirilgan polipropilen plyonka (BOPP), quyma polipropilen plyonka (CPP), poliolefin bilan puflangan plyonka (PP, PE), ikki o'qli yo'naltirilgan poliester plyonka (BOPET), ikki o'qli yo'naltirilgan neylon plyonka (BOPA)
