Organopolysiloxanes tig kho kev lag luam hauv 19th caug xyoo. Peb tab tom hais txog silicone thiab nws cov khoom siv, uas, ua tsaug rau lawv cov khoom tshwj xeeb, nws tau ua rau nws muaj peev xwm niaj hnub ua tiav ntau cov txheej txheem ob qho tib si hauv kev kho cov tshuab thiab hauv thaj chaw tshuaj.
Cov khoom siv silicone niaj hnub no feem ntau yog cov silicone tubing, cov pa roj, thiab cov ntsaws ruaj ruaj. Cov yam ntxwv ntawm silicone ua rau nws muaj peev xwm los ua haujlwm cov khoom ua los ntawm nws ntawm ntau yam kub, txawm tias qhov tseem ceeb. Yog li, qhov ua hauj lwm ntau ntawm ib lub raj roj silicone yog li ntawm -55 txog +290 degrees Celsius.
Cov tub ntxhais ua los ntawm silicone tiv taus ntau yam, xws li:
- kev cuam tshuam nrog cov roj ntxhia;
- hiav txwv dej thiab dej npau npau;
- ntau yam tshuaj lom neeg, alkalis, kua qaub, dej cawv;
- tsis kam mus rau ultraviolet hluav taws xob.
Silicone tub ntxhais zam lub cev deformation zoo, lawv tsis muaj tshuaj lom thiab tuaj yeem tiv taus hluav taws xob. Tsis tas li, qhov kev pabcuam lub neej ntawm cov yas tuaj yeem yuav txog 30 xyoo. Nyob ntawm cov qauv kev tsim tawm, txoj yas txhaws txawv xim.
Kho mob siv
Cov tshuaj, tej zaum feem ntau ntawm txhua qhov, yuav tsum muaj kev ris txiaj rau qhov nrhiav pom ntawm silicone thiab nws lub zog. Cov khoom siv no tau hloov lub impractical thiab feem ntau tsis zoo polyethylene cov ntaub ntawv. Niaj hnub no, silicone tubing siv los ua kom poob. Lawv siv rau hauv ntau cov cuab yeej siv kho mob rau kev muab tshuaj thiab cov cua sib xyaw, xws li, piv txwv, hauv cov cuab yeej siv rau kev nqus tshuaj loog thiab lub ntsws ua pa tawm. Cov hlab yog qhov tsis tseem ceeb uas ua rau ntau cov chaw tso dej tawm, raws li lawv tsis nkag rau hauv cov ntshav thiab tsis deform vim kub raug. Lawv cawm lub neej ntawm cov neeg mob postoperative thaum nws tsis tuaj yeem ua ntej.
Siv hauv thev naus laus zis
Hauv qhov txuj ci kev lag luam, cov tub ntxhais silicone siv los muab thiab tshem tawm cov kua dej ntau, cov kab hluav taws xob ntxig, tsim cov txheej tiv thaiv rau cov kav dej hauv qhov chaw xeb.
Piv txwv, hauv kev lag luam tsheb, cov kav dej siv los muab roj av rau lub cav thiab hauv lub nruab cua txias ntawm lub tsheb. Lawv tiv taus lub siab zoo, yog li lawv tuaj yeem siv kom txias ntau yam khoom siv thiab cov khoom siv.
Siv kev lag luam khoom noj khoom haus
Silicone leeg siv dav hauv kev lag luam khoom noj khoom haus, qhov uas lawv siv rau hauv ntau hom kev sib cais, sau cov kab, distillation chav nyob, rectification kem. Qhov no yooj yim heev vim tias silicone tsis muaj ntxhiab. Hauv cov kev teeb tsa no, cov tub ntxhais silicone ua kom zoo li cov kua xa mus rau kev ua thiab txuas ntxiv mus.
Cov hlab kuj tseem siv tsis tau hauv ntau qhov chaw sim tshuaj. Vim yog lawv lub zog, lawv tau siv ntau hauv kev sim rau kev cais cov tshuaj lom neeg tshiab thiab cov tshuaj lom neeg. Nyob rau ntawd, nrog kev pab ntawm cov kav dej, tshuaj lom neeg thiab tshuaj lom neeg muaj nyob rau hauv thiab ua tiav kom tau cov tshuaj tshiab.
