1.What cov nyhuv tsis muaj kub tsawg muaj ntawm kev kos tsis kam?
Kev hloov pauv hauv txheej txheej: Qhov ntsuas kub hloov pauv ntawm feem ntau cov txheej txheem organic yog 50-80 degree. Thaum lub ambient kub yog ntau dua li tg, kev txav ntawm txheej txheej molecular yog txwv, tab sis qhov yooj yim txo qis me ntsis thiab cov brittleness nce.
Khawb tsis kam:
Thaum khawb me ntsis, cov txheej me me "tawg" vim yog cov qov loj, ua rau cov khawb av uas sib sib zog nqus thiab txawm tias coating fragments peetring tawm.
Cov khoom sib txawv txawv txawv: ntawm -20℃ntawm cov txheej txheem PE tsawg dua 50%, thiab qhov kev pheej hmoo ntawm qhov cub hauv qab tom qab khawb av nce; Thaum cov tshuaj fluorocarbon muaj cov ntsiab molecular muaj zog molecular saw ruaj khov thiab tsawg dua brithleness nce ntawm tsawg kub, ua rau nws rov muaj kev ncaj ncees thaum kos.
2.Yog li cas chav tsev kub muaj nyob ntawm kos tsis kam?
Txheej Txheej Hloov Pauv: Lub sijhawm no, txheej txheem yog nyob rau hauv "kev ua kom zoo nkauj
Khawb tsis kam:
Cov khawb kev tiv thaiv yog qhov ruaj khov tshaj plaws, hauv paus nrog kev tsim qauv ntawm cov txheej nws tus kheej.
Kev khawb feem ntau yog "linear ntiav cov khawb av" uas tsis yooj yim los qhia rau hauv qab, thiab qhov pom ntawm cov khawb hauv tuaj yeem txo los ntawm lubricating additives nyob rau hauv txheej.
3.Yog li cas ua kom sov siab muaj qhov kub thiab txias muaj nyob ntawm kev kos tsis kam?
Txheej Txheej Kev Hloov: Thaum qhov kub tshaj lub TG ntawm cov txheej txheem, cov txheej txheem moleceries txo kom tsawg, thiab qhov yooj yim dhau lawm.
Khawb tsis kam:
Cov txheej tau yooj yim "nias" lossis "dragged" los ntawm cov khoom nyuaj ", ua rau cov khawb av dav thiab txawm tias txheej nplaum.
Cov Cuab Yeej Sib Txawv Sib Txawv Sib Txawv: Nyob rau 60 degree, tus mem hluav, tus lej ntawm chav sov yuav poob los ntawm 1h, thiab kos lub teeb nrog tus yuam sij tuaj yeem tawm ntawm cov cim pom tseeb; Thaum PVDF txheej muaj qhov TG siab dua thiab tseem tuaj yeem tswj hwm lub hardness dua ntawm 3h hauv qab 80℃yuav luag tsis hloov pauv.
4.Yog dab tsi cov av noo muaj ntawm kev kos tsis kam?
Kev hloov pauv ntawm txheej txheej: Yog tias cov txheej tsis kho tiav, cov av noo yuav ua rau muaj kev nkag mus rau hauv cov sib xyaw ua ke thiab txo cov hlua khi ntawm cov txheej; Nyob rau tib lub sijhawm, noo noo tej zaum yuav tsis muaj zog ntawm cov nplaum ntawm txheej thiab lub substrate, ua rau cov txheej ua kom zoo "yooj yim mus tev tawm".
Khawb tsis kam:
Thaum khawb, txheej yog qhov ntau dua yuav tau "nqa" lossis "delaminated", uas ua rau muaj kev puas tsuaj ntawm "kos + tev".
Rau cov resins uas muaj cov pab pawg hydrophilic, lub hardness yuav txo qis los ntawm 10%-20% nyob rau hauv siab humidity, thiab kos tsis muaj zog; Thaum PVDF muaj cov qauv hydrophobic molecular, thiab nws cov kev ua tau zoo yuav luag tsis hloov nyob rau hauv high agity.
5.What effect puas qis vaum muaj ntawm kev kos tsis kam?
Kev hloov pauv hauv cov txheej txheej: Lub chaw qhuav dej yuav ua kom nrawm dua qhov tso tawm ntawm cov khoom seem nyob hauv cov txheej. Yog hais tias tus txheej nws tus kheej tsis yog nyuaj txaus, nws yuav dhau los ua me ntsis vim yog "overrrying".
Khawb tsis kam:
Kev khawb tiv thaiv yog qis dua qis dua qhov ntsuas kub thiab cua sov. Nws yog qhov yooj yim dua los ua cov kab nrib pleb zoo thaum kos, thiab cov khawb thiab cov khawb kom yooj yim dua rau "whiten" vim yog qhov dryness.
Qhov cuam tshuam yog me me, feem ntau tsuas yog tsis muaj zog me me los yog cov resins tsawg, thiab yuav luag tsis cuam tshuam rau cov txheej txheem ua haujlwm siab xws li PVDF.
