Khoom nta:
A) Nws muaj peev xwm nqus tau ntawm ultraviolet teeb nyob rau hauv Ultraviolet spectrum (tshwj xeeb yog} {{} {{{{0} {300-400 lub teeb ruaj ruaj rau cov khoom siv yas.
B) Zoo heev sib raug zoo nrog thermoplastic Rawins, tshwj xeeb tshaj yog polyocefins, yog li ua kom muaj kev sib cais hauv cov polymer.
C) Tsawg evaporation siab siab, kom zam dhau cov khoom poob hauv cov txheej txheem.
D) Tsawg tsiv teb tsaws, tsis muaj tshuaj tsuag dej khov.
E) Zoo heev tshav kub tsis kam, tsis muaj qhov tseem ceeb thiab volatilization ntawm qhov ntsuas kub extrusion kub.
F) Kev siv tshuab hauv tshuaj hauv cov resins thiab kev hnav ris tsho feem ntau tsim los ntawm cov ntaub ntawv yas chaw tsim khoom.
G) tsis ua rau muaj ntxhiab tsw.
H) Tsis muaj kev coj dawb huv, tsis muaj kev cuam tshuam vim yog impurity.
Daim Ntawv Thov Khoom:
Polymer yog yooj yim cuam tshuam los ntawm ultraviolet lub teeb, ua rau kev hloov pauv ntawm cov khoom siv lub cev. Elastics txo qis rau xoom, cov ncuav ua cov nkig thiab poob cov tshuab muaj zog. Kuaj thiab kev coj ua sab nraud tau ua pov thawj tias 531 tiv thaiv polymer zoo heev
1. Polyethylene: Ob lub siab-ceev thiab qis-ntom polyethylene yog ua tau zoo heev. Cov kev siv tau pom zoo rau polyethylene tiaj yarns, monofilaments, thiab cov yeeb yaj kiab yog {}}. {}. 5%. Rau cov khoom lag luam qis dua thiab tshuab cov khoom siv-pwm, cov kev siv pom zoo yog {8}}}}. 3%. Nws ua cov yeeb yam zoo hauv cov yeeb yaj kiab ua liaj ua teb, nthuav lawv lub neej los ntawm {{11 {} sij hawm. Cov lus pom zoo yog 0. 5%
2. Polypropylene: 531 yog ua tau zoo heev hauv ob qho xim thiab tsis muaj kob polypropylene. Tus nqi ntawm UV absorber nce nrog txo cov khoom tuab. Fiber ntau, monofilament, dawb xov paj, roj, net thiab yeeb yaj kiab siv: 0. 5%. Txhaj Tshuaj Pwm: {{0}. 2-0. 3%
3. Pvc: dog dig pvc, seb puas yog, yuav daj thiab hloov nws lub cev hauv qab UV teeb, tshwj xeeb tshaj yog cov yas yas yuav tsim cov me me rau saum npoo. Qhov raug ntxiv ntawm cov yog: mos PVC: 0. 3-2%. HARD PVC: {0. 3%
4. Rau SBS thiab PS hloov kho TPR cov khoom siv, cov tshuaj ntau yog 0. 3%
5. Lwm tus: Kev Pom Zoo Dosage: 0}. 1-0. 3%. Ua ntej siv, ib qho kev kuaj me me yuav tsum tau ua los txiav txim siab cov mis kawg
Kev Nyab Xeeb, kev nyab xeeb thiab chaw cia khoom rau tib neeg cov tawv nqaij, nyab xeeb kev tuav thiab kev ua haujlwm; Thaum khaws cia, nws yuav tsum khaws cia kom qhuav thiab muab tso rau hauv qhov chaw txias.
