PBT yog dab tsi thiab vim li cas nws thiaj siv dav heev?

Polybutylene Terephthalate (PBT) yog ib qho thermoplastic ua haujlwm siab uas tsim los ntawm butylene glycol thiab terephthalic acid, nrog cov yam ntxwv zoo ib yam li Polyethylene Terephthalate (PET). Ua ib tug tswv cuab ntawm tsev neeg polyester, PBT siv dav hauv tsheb, khoom siv hluav taws xob, thiab cov khoom siv precision vim nws cov khoom siv kho tshuab muaj zog, kev ruaj khov thermal zoo heev, kev rwb thaiv hluav taws xob, kev tiv taus cov tshuaj lom neeg, thiab dej noo. Cov txiaj ntsig no ua rau nws yog cov khoom siv nyiam rau cov khoom siv sib txuas, cov tsev, thiab cov khoom siv sab hauv.

Vim li cas cov teeb meem ntawm qhov chaw hauv PBT thiaj li dhau los ua qhov kev txhawj xeeb loj hlob hauv cov ntawv thov kev lag luam siab?

Raws li kev lag luam xws li tsheb, khoom siv hluav taws xob, thiab kev tsim kho kom raug tsa tus qauv rau cov khoom siv zoo nkauj thiab ruaj khov, Polybutylene Terephthalate (PBT) - ib qho yas siv dav dav - ntsib kev nyuaj siab kom xa tau qhov zoo tshaj plaws ntawm qhov chaw.

Txawm hais tias nws muaj zog thiab thermal profile, PBT yooj yim raug qhov tsis zoo ntawm qhov chaw thaum lub sijhawm ua haujlwm - tshwj xeeb tshaj yog thaum raug cua sov, shear, lossis noo noo. Cov qhov tsis zoo no tsis yog tsuas yog cuam tshuam rau qhov zoo li ntawm cov khoom xwb tab sis kuj tseem cuam tshuam rau kev ua haujlwm ntawm cov khoom.

Raws li cov ntaub ntawv kev lag luam, cov teeb meem ntawm qhov chaw feem ntau hauv cov khoom PBT suav nrog:

• Cov Kab Nyiaj/Cov Cim Dej: Cov qhov tsis zoo uas tshwm sim ua cov qauv radial ntawm qhov chaw ntawm cov khoom los ntawm cov dej noo, cua, lossis cov khoom siv carbonized ua raws li kev taw qhia ntawm cov dej ntws

• Cov Cim Cua: Qhov chaw poob qis lossis cov npuas tsim thaum cov pa roj hauv cov yaj tsis tawm tag

• Cov Cim Ntws: Cov qauv nto uas tshwm sim los ntawm cov khoom ntws tsis sib npaug

• Cov nyhuv ntawm txiv kab ntxwv tev tawv: Cov qauv nto zoo li txiv kab ntxwv tev tawv

• Kev khawb ntawm qhov chaw: Kev puas tsuaj ntawm qhov chaw los ntawm kev sib txhuam thaum siv

Cov teeb meem no tsis yog tsuas yog cuam tshuam rau qhov zoo nkauj ntawm cov khoom xwb tab sis kuj tseem yuav ua rau muaj teeb meem kev ua haujlwm. Cov teeb meem khawb ntawm qhov chaw yog qhov tseem ceeb hauv cov khoom siv sab hauv tsheb thiab cov khoom siv hluav taws xob, nrog rau cov ntaub ntawv qhia tias ntau dua 65% ntawm cov neeg siv khoom xav tias qhov tsis kam khawb yog qhov tseem ceeb thaum ntsuas qhov zoo ntawm cov khoom.

Cov Chaw Tsim Khoom PBT Yuav Ua Li Cas Thiaj Kov Yeej Cov Teeb Meem Ntawm Qhov Chaw No?Kev Tsim Khoom Siv Tshiab!

Kev Siv Tshuab Hloov Kho Sib Xyaws:Cov khoom siv Ultradur® Advanced series PBT tshiab ntawm BASF siv cov thev naus laus zis hloov kho ntau yam khoom sib xyaw ua ke, ua rau qhov nyuaj ntawm qhov chaw thiab kev tiv thaiv khawb los ntawm kev ntxiv cov feem pua ​​tshwj xeeb ntawm PMMA rau hauv PBT matrix. Cov ntaub ntawv sim qhia tau tias cov khoom siv no tuaj yeem ua tiav qhov nyuaj ntawm cwj mem ntawm 1H-2H, ntau dua 30% ntau dua li PBT ib txwm muaj.

Kev Siv Tshuab Nano-txhim Kho:Covestro tau tsim cov nano-silica enhanced PBT formulations uas ua rau qhov nyuaj ntawm qhov chaw nce mus txog 1HB theem thaum tswj cov khoom siv pob tshab, txhim kho kev tiv thaiv khawb los ntawm kwv yees li 40%. Cov thev naus laus zis no yog qhov tsim nyog rau cov khoom siv sab hauv tsheb thiab cov khoom siv hluav taws xob siab heev uas muaj cov kev cai nruj heev.
