Tus nqi zoo High Styrene Roj Hmab / HSR 60 / HSR 68 / HSR 80 / HSR 85
Cov roj hmab styrene siab yog ib hom roj hmab styrene butadiene tshwj xeeb. Nws yog cov polymer tsis-polar uas tau npaj los ntawm kev sib koom ua ke ntawm styrene thiab butadiene latex. Cov qauv tshuaj lom neeg:
—(CH2—CH=CH—CH2)m—(CHC6H5—CH2)n—
Nws yog cov hmoov dawb, tsis muaj tshuaj lom, tsis muaj ntxhiab thiab yooj yim hlawv. Qhov kub ntawm kev hloov pauv kub: 70-90 ℃, dawb khov. Nws yog siv los ua tus neeg sawv cev rau kev txhim kho qhov nyuaj, kev laus-ua hauj, kev hnav-ua hauj, lub zog tsim kua muag thiab lub zog tensile ntawm cov roj hmab. Muaj cov thermoplasticity zoo heev thiab cov khoom siv hluav taws xob rwb thaiv tsev.
Cov roj hmab styrene siab yog qhov tsim nyog rau kev tsim cov khoom lag luam uas muaj zog thiab qis.
1. Ua khau: khau tawv, pob luj taws, khau ua npuas ncauj tawv, khau tawv cuav thiab lwm yam;
2.Raws li cov ntaub ntawv hauv pem teb: roj hmab hauv pem teb pobzeb; cov khoom lag luam, xws li roj hmab yob, tshuab ntxhua khaub ncaws, roj hmab tawv thiab lwm yam khoom siv daim txhuam cev;
3. Kev lag luam kis las: pob, rollerskate;
4. Cov khoom siv hluav taws xob rwb thaiv tsev;
5. Cov log tsheb kauj vab zoo; ntau yam luam ntawv pastern roller; roj hmab slab;
6.ABS, AS yas;
Nyob rau xyoo tas los no, cov teb roj hmab tau them sai sai rau kev txhawb nqa cov roj hmab styrene siab, tshwj xeeb tshaj yog nyob rau hauv kev lag luam tsheb, xws li siv rau hauv lub log tsheb. Yog li ntawd, kev ua lag luam muaj peev xwm ntawm HSR yog loj heev. Peb lub HSR tuaj yeem hloov Nyiv lub NIPOL HS850, HS860 & HS870, JSR0060 thiab KER1904 thiab HS260 thiab lwm yam.
Hauv lub hnab yas sib xyaw ua ke uas muaj zog heev thiab muaj PE txheej rau hauv lub hnab ntaub/lub hnab ntawv kraft, qhov hnyav tag nrho yog 20kg. Tiv thaiv hluav taws, dej thiab tshav ntuj. Khaws cia rau qhov chaw txias thiab cua nkag.
