Taw qhia
Chloroprene roj hmab SN242 yog siab zog, nws yog tau los ntawm mercaptan hloov thiab Chloroprene monomer los ntawm emulsion polymerization nrog siab tus nqi ntawm crystallization, rau siv ib tug Nairit daim ntawv qhia thiab txheej txheem technology. Nws tuaj yeem pom zoo ib yam li Dupont AD-20 ntawm Tebchaws Meskas.
Yam ntxwv
1. Ceev ceev ntawm crystallization thiab muaj zog cohesion; Nruab nrab viscosity ntawm SN24- series thiab tuaj yeem yaj hauv toluene lossis cov kuab tshuaj sib xyaw;
2. Zoo solubility thiab uniformity tshaj CR244 thiab zoo cia stability;
3.Adhesive cements npaj los ntawm SN242 yog lub teeb nyob rau hauv cov xim thiab siab bonding zog, ceev zoo grips, yooj yim tuav, adhesion txheej kom ib tug ntev lub sij hawm;
4. Zoo resistant rau ozone, huab cua, roj, tshuaj corrosion thiab extension ntawm cov nplua yog tsis flammable;
5. SN242 tuaj yeem muab faib ua SN242A thiab SN242B, SN242A yog ze rau A90 thiab tuaj yeem siv tau raws li qib kawm ntawm kev npaj grafted nplaum;
6. SN242B yog ze rau AD-20, feem ntau yog npaj kho kom zoo nkauj nplaum thiab lwm yam.
Qhov tshwm sim
Dawb los yog lub teeb daj chips, nrog talcum raws li ib tug tso tawm neeg sawv cev, tsis muaj mechanical impurities.

Daim ntawv thov
SN242, uas yog cov khoom siv raw rau kev npaj cov nplaum nplaum, tuaj yeem siv ib leeg lossis ua ke nrog lwm hom yog qib feem ntau ntawm kev npaj cov nplaum. Adhesive yog tsim rau kev sib txuas ntawm kev lag luam khau, roj hmab tawv, ntoo, hlau thiab cov ntaub ntawv siv.
