Khoom noj khoom haus qib hose yog dawb ntawm plasticizers Khoom noj khoom haus qib hose phab ntsa yog synthesized los ntawm tshwj xeeb sab saum toj-qib polyether-polyurethane (E-PUR), kiag li tsis muaj organic plasticizers, phthalates thiab latex ntxiv thiab lwm yam teeb meem tshuaj.
Khoom noj khoom haus-qib steel hlau hose yog Pu raw khoom tuaj ntawm lub teb chaws Yelemees, uas yog ib tug Pu steel hlau hose nrog ib tug embedded steel hlau ncej. Cov phab ntsa sab hauv thiab sab nrauv yog pob tshab, tsis muaj npuas, thiab kev xa tawm yog pom meej; low-concentration acid thiab alkali tsis kam, siab elasticity, tsis yooj yim rau hnub nyoog, thiab kev pab lub neej ntev; Nws muaj qhov zoo ntawm kev ua haujlwm rau qee qhov tsis zoo siab thiab tshuaj lom neeg corrosion. Muaj peev xwm tiv taus qhov ruaj khov ntawm li ntawm -30 degree rau ntxiv rau 90 degree, thiab tuaj yeem ncav cuag ntxiv 120 degree hauv lub sijhawm luv luv, them nrog lub zog elastic tooj liab-plated steel hlau ntawm cov yeeb nkab phab ntsa; phab ntsa: tshwj xeeb sab saum toj-qib polyether-polyurethane, du sab hauv phab ntsa; Qhov zoo tshaj plaws Khoom noj khoom haus qib hoses yog ntau tshaj 10 npaug ntau hnav-resistant dua li PVC hoses thiab roj hmab hoses.
Khoom noj khoom haus-qib steel hlau hose yog qhov kev xaiv zoo tshaj plaws rau kev sib kis ntawm ntau yam kua dej. Nws muaj cov yam ntxwv ntawm lub teeb yuag, softness, zoo elasticity, corrosion kuj, hydrolysis tsis kam, siab transparency, non-toxic thiab tasteless, me me dabtsi yog khoov vojvoog thiab zoo tsis zoo siab tsis kam. Tsis pub dawb ntawm cov organic plasticizers, phthalates thiab latex additives thiab lwm yam khoom tsis zoo, lub hauv paus ntsiab lus ntawm kev ua ntawm plasticizers yog tias cov plasticizer molecules yog cov khoom me me (xws li cov yas thiab cov roj hmab ntawm cov ntaub ntawv polymer), lawv muab tso rau ntawm cov khoom siv polymer molecular los ntawm cov txheej txheem sib ntxiv, ua kom tsis muaj zog ntawm kev ntxhov siab ntawm cov polymer molecular chains los ntawm kev thaiv, thaiv, lubricating, nce qhov kev ncua deb, thiab lwm yam, ua rau kom muaj zog ntawm cov khoom siv polymer molecular chains xws li plastics, crystallinity ntawm polymer molecular saw txo qis, yog li ua kom muaj zog ntawm polymer molecular chains. plasticity ntawm lub polymer. Txawm li cas los xij, cov plasticizers no tsis siv rau hauv cov khoom siv raw ntawm cov khoom noj khoom haus zoo-qib steel hlau hose.
Khoom noj khoom haus qib steel hlau hose muaj cov khoom ntawm tensile lub zog, muaj zog nro, siab tsim kua muag zog, puas kuj, dabtsi yog khoov tsis kam, nkag mus rau, tsis kub tsis kam, hydrolysis kuj, thiab lwm yam. Nws yog non-toxic thiab tasteless, thiab cov khoom noj khoom haus yuav tsis decompose nyob rau hauv lub raj. Cov ntxhiab tsw, du hauv lub raj phab ntsa, zoo heev fluidity, siab transparency ntawm lub raj phab ntsa, qhov ntws ntawm nruab nrab hauv lub raj tuaj yeem pom, muaj zog hnav tsis kam, zoo siab tsis kam, thiab hluav taws xob zoo li qub tuaj yeem tawm los ntawm cov av ntawm cov kauv. steel hlau.
Nws tau dhau los ntawm SGS qhov chaw kuaj FDA thiab 18 lub teb chaws cov khoom siv plasticizer, thiab tuaj yeem siv dav hauv kev lag luam khoom noj, cawv, dej haus thiab kev noj qab haus huv. Nws yog cov yeeb nkab zoo tshaj plaws rau kev thauj khoom noj, dej haus, mis nyuj, jam, siab concentration cawv thiab lwm yam xov xwm.
