HTV, LSR, HCR, RTV2 SILICONE Rubber

LSR (Liquid Silicone Rubber) yog cov khoom siv ntau yam khoom siv silicone siv hauv ntau yam kev lag luam. Cov kua silicone yog nchuav los yog txhaj rau hauv pwm thiab tom qab ntawd kho. LSR yog siv nyob rau hauv kev kho mob, tsheb thiab cov neeg siv khoom daim ntawv thov vim nws muaj peev xwm los tsim complex geometries nyob rau hauv ib tug luv luv lub sij hawm thiab nws zoo heev sealability. Qhov zoo ntawm LSR suav nrog biocompatibility zoo heev vim nws tsis muaj tshuaj lom, ua haujlwm nyob rau hauv qhov kub thiab txias ({1}} degree F - 500 degree F) thiab UV tsis kam. Qhov tsis zoo ntawm LSR suav nrog cov nqi siab thiab lub sijhawm kho ntev.

RTV2 (Room Kub Vulcanizing Silicone) yog lwm hom silicone uas siv rau hauv ntau daim ntawv thov. Qhov no ob feem silicone system yog tov kom huv si ua ntej siv thiab reacts raws li kev sib cuag tom qab kho. Nws tuaj yeem siv rau hauv cov xwm txheej uas yuav tsum tau muaj cov roj hmab ruaj khov heev. Qhov zoo ntawm RTV2 suav nrog lub sijhawm kho tam sim thiab tiv thaiv qhov kub thiab txias (-65 degree F - ntxiv rau 400 degree F). Qhov tsis zoo vim yog txheej txheem kho muaj xws li qis zog tensile thiab tsawg tus naj npawb ntawm cov xim xaiv los ntawm.

HCR (Heat Cured Rubber) yog ib feem ntawm cov khoom siv silicone siv hauv kev tsim khoom ntawm ntau yam khoom. Cov khoom siv silicone no tau kho nrog cua sov, yog li tshem tawm qhov xav tau los sib xyaw ua ke ob feem. HCR yog qhov zoo tshaj plaws rau kev tsim khoom loj vim nws nrawm dua, tsis tshua muaj nqi, thiab yuav tsum tau kho me ntsis tom qab kho. Qhov zoo muaj xws li tiv thaiv qhov kub thiab txias ({3}} degree F – ntxiv rau 400 degree F) thiab ntau yam xim. Disadvantages suav nrog cov tshuaj tsis zoo thiab tsis muaj zog.

HTV (High Temperature Vulcanizing Silicone) yog ob feem ntawm silicone uas ua haujlwm tom qab raug tshav kub. Nws yog siv rau hauv kev tsim cov khoom ua haujlwm siab thiab muab cov txiaj ntsig ntawm kev kho sai, lub zog tensile siab, thiab kub tsis kam (-90 degree F - ntxiv rau 500 degree F). Qhov zoo ntawm HTV suav nrog ntau yam kev thov ntau yam thiab cov khoom siv hluav taws xob zoo heev. Qhov tsis zoo suav nrog cov nqi teeb tsa kim thiab lub sijhawm ua haujlwm tsawg vim yog lub voj voog kho.
