Cov khoom siv ntawm lub cable kuj tseem ua lub luag haujlwm txiav txim siab hauv qhov zoo ntawm cable. yav dhau los, yas cables tau siv ntau zaus, tab sis maj mam roj hmab cables pib hloov cov yas cables. Yog li yog vim li cas cov roj hmab cable yuav tsum yog qhov zoo tshaj plaws. Ntawm no cia ZMS cable tuam txhab editor piav qhia qhov txawv ntawm roj hmab thiab yas.
Dav lus dav, Roj Hmab yog ib hom yas thiab yas suav nrog roj hmab.
Qhov tseem ceeb tshaj qhov sib txawv ntawm cov yas thiab roj hmab yog tias cov yas deforms thaum yas deformation, thaum roj hmab yog elastic deformation. Hauv lwm lo lus, Nws tsis yog yooj yim los kho qhov qub lub xeev ntawm cov yas tom qab deformation, thaum roj hmab kuj yooj yim dua.
Lub elasticity ntawm yas yog tsawg heev, feem ntau tsawg dua 100%, thaum roj hmab tuaj yeem ncav cuag 1000% los yog ntau dua. Feem ntau ntawm cov txheej txheem molding ntawm cov yas yog ua tiav raws li cov txheej txheem molding ntawm cov khoom kuj tiav. Thaum cov txheej txheem roj hmab molding tiav tom qab qhov xav tau ntawm cov txheej txheem vulcanization.
Cov yas thiab roj hmab yog tib yam khoom siv polymer, Feem ntau yog tsim los ntawm ob lub atom ntawm carbon thiab hydrogen, thiab qee qhov muaj cov pa me me, nitrogen, tshuaj chlorine, silicon, tshuaj fluorine, sulfur, thiab lwm yam atoms.
Nws cov khoom yog tshwj xeeb thiab nws siv tshwj xeeb. Nyob rau hauv chav tsev kub, yas yog khoom, nyuaj, thiab tsis tuaj yeem ncab thiab deformed. Thaum cov roj hmab tsis tawv, los yog elastic, tuaj yeem ncab kom ntev dua, nres ncab, thiab tuaj yeem rov qab mus rau nws qhov qub qub. Qhov no yog vim qhov txawv ntawm lawv cov qauv molecular.
Lwm qhov txawv yog tias cov yas tuaj yeem siv tau thiab rov siv tau ntau zaus, thaum cov roj hmab tsis tuaj yeem siv ncaj qha, tab sis tsuas yog tom qab ua tiav rau hauv cov roj hmab rov qab, thiab tom qab ntawd muaj. Daim ntawv yas ntawm tshaj 100 rau 200 degrees zoo ib yam li cov roj hmab ntawm 60 rau 100 qib. Cov yas tsis suav nrog roj hmab.
Taw Qhia Rau Roj Hmab Hlau Thiab Cable Chlorosulfonated Polyethylene Rubber Daim Ntawv Thov
Hom
Chlorosulfonated polyethylene yog derivative ntawm polyethylene. nyob ntawm cov ntsiab lus chlorine thiab polyethylene molecular hnyav, chlorosulfonated polyethylene roj hmab muaj chlorosulfonated polyethylene 20, chlorosulfonated polyethylene 30, chlorosulfonated polyethylene 40, chlorosulfonated polyethylene 45. tus hlau thiab cable kev lag luam Feem ntau siv chlorosulfonated polyethylene 20, thiab chlorosulfonated polyethylene 40.
Yam ntxwv
1. Muaj lub cev zoo thiab cov khoom siv kho tshuab.
2. Nws muaj cov cua kub zoo thiab tuaj yeem siv tsis tu ncua ntawm qhov kub thiab txias 120 ℃.
3. Zoo heev ozone kuj, tshav ntuj tiv thaiv, thiab atmospheric aging kuj, sab nraum zoov raug rau rau xyoo tsis tawg.
4. Zoo nplaim taws, thib ob tsuas yog fluorine roj hmab thiab neoprene.
5. Cov tshuaj tiv thaiv zoo heev.
6. Zoo roj tsis kam.
7. Kev tiv thaiv zoo rau corona thiab hluav taws xob.
8. Nws muaj cov txheej txheem ua tau zoo thiab tuaj yeem siv nrog lwm cov roj hmab.
Qhov tsis zoo ntawm chlorosulfonated polyethylene roj hmab yog me ntsis loj compression deformation thiab ua haujlwm tsis zoo ntawm qhov kub thiab txias.. Tab sis vim nws qhov zoo, nws yog ib qho zoo heev roj hmab hauv hluavtaws roj hmab.
Chlorosulfonated polyethylene 40 feem ntau yog siv rau rwb thaiv tsev thiab sheathing, thiab chlorosulfonated polyethylene 20 tuaj yeem siv rau qhov hluav taws xob qis hluav taws xob rwb thaiv tsev.
Roj Hmab Hlau Thiab Cable Nrog Silicone Roj Hmab
Ua ntej tshaj plaws, silicone roj hmab yog cov roj hmab tshwj xeeb, tshwj xeeb hauv nws cov cua sov ua haujlwm zoo heev.
Qhov kub tsis kam yog vim nws cov saw hlau molecular muaj (-Thiab -O-) daim ntawv cog lus, silicon-oxygen bonding zog dua carbon bonding ntau loj 456>348kJ/mol, thiab Si yog ib qho uas tsis yog-combustible, nrog cov yam ntxwv ntawm cov ntaub ntawv inorganic, yog li qhov kub tsis kam yog siab. Silicone roj hmab muaj softness, tuaj yeem tiv thaiv ozone, yas, thiab nplaim taws, muaj kev rwb thaiv tsev zoo, siab thiab qis-kub tsis kam (-60-200 ℃), thiab corona kuj thiab arc kuj zoo heev, yog kev tsim cov hlau thiab cable zoo thiab txhim khu kev qha cov ntaub ntawv.
Thib ob, txias tsis kam, ua ke nrog kev tiv thaiv tshav kub yog hais tias silicone roj hmab ua haujlwm kub ntau yog dav heev, tib yam li saum toj no kuj yog vim li cas yog tias daim ntawv cog lus lub zog loj.
Kuj tseem muaj roj ua haujlwm zoo, hnyav kuj, hluav taws xob tsis kam thiab nplaim hluav taws, thiab zoo pwm kuj; ntxiv rau, tasteless thiab non-toxic, tsis muaj kev phom sij rau tib neeg kev noj qab haus huv thaum siv.
Tab sis nws kuj muaj qhov tsis zoo: Lub zog tensile, kua muag zog, thiab abrasion tsis kam ntawm chav tsev kub yog qis dua li cov roj hmab ntuj thiab lwm yam roj hmab hluavtaws, tsis zoo acid thiab alkali tsis kam, thiab kim, kev ua haujlwm tsis zoo.
Vinyl silicone roj hmab tsis hais txog kev ua haujlwm, lub cev thiab mechanical zog, kub-kub kuj, thiab compression mus tas li deformation hauv silicone roj hmab yog qhov zoo thiab muaj ntau daim ntawv thov hauv kev lag luam cable.
Cov no yog qhov sib txawv thiab qhov zoo thiab qhov tsis zoo ntawm roj hmab cables thiab yas cables nyob rau hauv ntau yam. Tsis muaj teeb meem dab tsi siv cable, ntev npaum li nws tsim nyog, nws yuav tsum zoo siv. ZMS cable tau nyob hauv kev lag luam rau ntau tshaj kaum xyoo, nqa cov cables zoo dua thiab ntau dua rau peb cov neeg siv khoom, nrog nruj kev tswj xyuas kev tsim nyog, siab ntseeg.
