Cov txheej txheem ntawm silicone tubing integrates cov ntaub ntawv science thiab precision manufacturing technology, feem ntau muab faib ua tsib theem: raw khoom npaj, sib tov thiab refining, extrusion molding, vulcanization, thiab kev soj ntsuam zoo.
1. Nyob rau theem kev npaj cov khoom siv raw, siab -cov roj hmab silicone zoo yog xaiv los ua cov khoom tseem ceeb, thaum cov khoom siv ntxiv xws li silica, crosslinking agents, fillers, thiab pigments ntxiv raws li cov khoom yuav tsum tau ua. Silica txhim khu lub hardness thiab lub zog ntawm silicone tubing, thaum crosslinking cov neeg ua haujlwm kom cov khoom muaj kev ruaj ntseg ntawm qhov kub thiab txias.
2. Nyob rau theem sib xyaw thiab ua kom zoo dua qub, cov roj hmab silicone nyoos thiab ntau yam khoom ntxiv tau ntxiv rau lub tshuab kaw ntom nti lossis ob - yob zeb raws li cov qauv sib piv, thiab rov ua kom zoo dua ua kom cov khoom sib npaug sib npaug. Cov txheej txheem no yuav tsum muaj kev tswj xyuas nruj ntawm qhov kub thiab txias kom ntseeg tau tias qhov sib tov melts thiab tsim cov tshuaj txhuam nrog zoo flowability, nteg lub hauv paus rau tom ntej extrusion molding.
3. Nyob rau hauv lub extrusion molding theem, pretreated silicone roj hmab compound yog pub rau hauv ib tug extruder thiab extruded mus rau hauv ib tug tubular zoo nyob rau hauv kub kub thiab siab los ntawm ib tug tuag. Tus tsim tuag yuav tsum xav txog yam xws li qhov loj me, cov duab, thiab phab ntsa thickness ntawm silicone tubing. Thaum lub sij hawm extrusion, ceev, kub, thiab siab yuav tsum tau tswj nruj me ntsis kom ntseeg tau tias cov phab ntsa tuab thiab du nto. Tom qab extrusion, silicone tubing yuav tsum tau txias thiab zoo li tus kom pib kho nws cov duab.
4. Vulcanization yog ib kauj ruam tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm silicone tubing. Extruded silicone tubing yuav tsum tau ua kom siab - kub vulcanization los tsim ib tug peb - qhov ntev network qauv ntawm silicone roj hmab molecules, yog li tau txais ntau dua elasticity thiab kub ua hauj. Qee cov khoom lag luam kuj xav tau cov vulcanization theem nrab kom tshem tawm cov ntxhiab thiab tiv thaiv kom tsis txhob tawg.
5. Kev tshuaj xyuas zoo yog ua tiav thoob plaws tag nrho cov txheej txheem tsim khoom. Cov khoom tiav yuav tsum tau ua ntau yam kev soj ntsuam, suav nrog kev tshuaj xyuas qhov muag, ntsuas phab ntsa tuab, ntsuas tensile, ntsuas kub tsis kam, thiab ntsuas hluav taws xob ua haujlwm, kom ntseeg tau tias lawv tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig hnyav. Tsuas yog silicone tubing uas dhau kev soj ntsuam nruj zoo tuaj yeem nkag mus rau theem tom ntej siv.
