Nws tuaj yeem tiv taus 327 degree siab kub.
Lub crystallinity ntawm raw khoom siv yog 90 ~ 95 feem pua, thiab melting kub yog 327 ~ 342 degree.
Lub npe tshuaj ntawm cov khoom siv raw yog polytetrafluoroethylene. Tus txheeb ze molecular hnyav ntawm polytetrafluoroethylene kuj loj, xws li los ntawm pua pua txhiab rau cov qis mus rau kaum lab rau cov siab, feem ntau lab (polymerization degree yog 104, thaum polyethylene tsuas yog 103).
1. Thaum siv cov khoom siv raw khoom siv, nws yuav tsum tau muab sau tseg tias siv nws li qub tuaj yeem txhim kho cov nyhuv, thiab yog tias nws siv tsis raug, nws yuav txo qhov kev ua haujlwm.
2. Feem ntau, cov khoom siv raw khoom siv yuav tsum raug mob raws cov xov kev taw qhia. Nws tsis raug tso cai los qhwv tag nrho cov xov nrog raw khoom siv. Thaum cov khoom siv raw khoom nkag mus rau hauv cov yeeb nkab, qhov kev sib khi yuav raug txo. Nws yog ib txoj hauv kev zoo dua los pib winding los ntawm cov hniav nyiaj hniav kub thib ob, tawm hauv cov hniav txhob lo lo ntxhuav pem hauv ntej.
3. Kev ceev faj yuav tsum tau them thaum lub sij hawm winding kom ntseeg tau tias cov khoom siv raw siv tsis tau rub tawm, thiaj li ua kom cov khoom siv raw khoom ruaj khov thiab nruj thiab muaj kev sib khi zoo dua hauv kev siv tom qab.
4. Raws li cov lus nug ntawm yuav ua li cas muaj pes tsawg lub voj voog los qhwv cov khoom siv raw, nws yuav tsum tau txiav txim siab raws li cov kev paub tshwj xeeb ntawm tus tswv kho kom zoo nkauj. Feem ntau, lub thickness ntawm lub thib ob ib nrab ntawm raw cov ntaub qhwv tawm yog loj, uas yog, nws yog thinner nyob rau hauv pem hauv ntej thiab thicker nyob rau hauv lub nraub qaum, uas yuav xyuas kom meej tias cov screws ua ntau thiab ntau nruj nyob rau hauv tus txheej txheem ntawm kev sib hloov. txhim kho kev sealing kev ua tau zoo.
5. Tom qab cov khoom siv raw khoom yog qhov txhab, tsis txhob thim cov xov thaum ntsia hlau ntsia hlau, txwv tsis pub nws yuav tsum tau rov ua dua thiab nruj.
