Siv Plumbers Daim Kab Xev

Khoom Qhia:

Siv Plumbers Daim Kab Xev yog ib qho khoom siv feem ntau siv hauv kev teeb tsa cov kav dej. Nws tau siv ntawm qhov txuas ntawm cov yeeb nkab txuas ntxiv txhawm rau txhim kho airtightness ntawm cov yeeb nkab txuas.

Siv Plumbers Daim Kab Xev yog qhov tshiab thiab cov khoom ntim zoo tagnrho. Nws tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab muaj kev sib khi zoo heev, rwb thaiv tsev thiab tiv taus xeb.

Cov khoom siv tshuaj ntawm Siv Plumbers Daim Kab Xev

Rwb thaiv tsev: Tsis cuam tshuam los ntawm ib puag ncig thiab zaus, qhov ntim tsis kam tuaj yeem ncav cuag 1018 ohm · cm, qhov hluav taws xob poob qis me me, thiab qhov hluav taws xob tawg yog siab.

Kub thiab qis tiv taus kub: cuam tshuam me ntsis ntawm qhov kub, qhov kub ntau, qhov ntsuas kub -190 ~ 260 ℃.

Lubricating tus kheej: Nws muaj qhov coefficient tsawg tshaj plaws ntawm kev sib txhuam ntawm cov yas thiab yog cov khoom siv roj uas tsis muaj roj zoo tagnrho.

Qhov tsis-nplaum: paub cov ntaub ntawv khoom tsis tuaj yeem ua rau saum npoo, nws yog cov khoom siv nrog lub zog me tshaj plaws.

Huab cua tsis kam, hluav taws xob tiv taus thiab tsis muaj permeability: raug rau huab cua mus sij hawm ntev, saum npoo thiab kev ua haujlwm tseem tsis hloov pauv.

Corrosion tsis kam: tshuaj lom neeg thiab huab cua tsis kam. Tshwj tsis yog rau cov hlau alkali yaj, PTFE tsis yog corroded los ntawm cov tshuaj reagents. Piv txwv li, nyob rau hauv cov tshuaj sulfuric acid, nitric acid, hydrochloric acid, lossis txawm tias hau hauv aqua regia, nws qhov hnyav thiab kev ua haujlwm tsis muaj kev hloov pauv, thiab nws yuav luag tsis yaj hauv txhua cov kuab tshuaj. Nws tsuas yog me ntsis soluble hauv txhua qhov alkanes (li 0.1g/100g) siab dua 300 ° C. PTFE tsis nqus dej, tsis kub hnyiab, thiab ruaj khov heev rau cov pa oxygen thiab ultraviolet rays, yog li nws muaj huab cua tiv taus zoo heev.

Lub cev muaj zog ntawm Kev Siv Plumbers Daim Kab Xev

Cov khoom siv dag zog ntawm PTFE yog qhov muag. Muaj lub zog qis heev.

Hauv cov ntawv thov ua haujlwm, ntau daim kab xev raw cov ntaub ntawv siv los siv cov khoom siv raw cov ntaub nplaum. Cov khoom siv raw cov kua nplaum muaj cov yam ntxwv ntawm kev sib zog ua kom muaj zog, ua haujlwm tau zoo, tiv taus xeb, tiv taus kub thiab tiv taus kev laus. Cov cuab yeej lim tau zoo, Kev teeb tsa nrawm, tam sim no yog cov xov xov tshaj plaws. Nws tau siv dav rau xov sib khi thiab kaw cov kav dej thiab kev tsim kho pej xeem xws li kev tua hluav taws, kev tsim nkoj, roj nkev, kais dej, ntsuas, ntsuas cua txias, cov pa roj, cov kav dej, thiab cov kav dej hydraulic.

Tsis-combustibility: Cov pa oxygen txwv qis dua 90.

Cov khoom siv kho tshuab: Nws qhov kev sib txhuam coefficient yog qhov tsawg heev, tsuas yog 1/5 ntawm polyethylene, uas yog qhov tseem ceeb ntawm perfluorocarbon nto. Ib qho ntxiv, vim tias cov tshuaj fluorine-carbon cov kab sib cuam tshuam hauv lub cev muaj zog tsawg heev, PTFE tsis nplaum.

Kev tiv thaiv kub: PTFE tswj cov cuab yeej zoo hauv qhov kub ntau ntawm -196 txog 260 ° C. Ib qho ntawm cov yam ntxwv ntawm perfluorocarbon polymers yog tias lawv tsis nkig ntawm qhov kub tsawg.

Cov khoom siv hluav taws xob: PTFE muaj cov hluav taws xob qis tsis tu ncua thiab dielectric poob hauv qhov ntau zaus, thiab muaj qhov hluav taws xob tawg loj, ntim tsis kam thiab tiv taus arc.

Kev tiv thaiv hluav taws xob: PTFE muaj hluav taws xob tiv taus tsis zoo (104 rads). Nws yuav txo qis tom qab raug rau hluav taws xob hluav taws xob siab, thiab cov khoom siv hluav taws xob thiab cov khoom siv ntawm cov polymer yuav txo qis.
