FAQ
Q: Dab tsi yog qhov zoo ntawm CR qaum tshaj EPDM qaum rau sab nraum zoov siv?
A: CR (Chloroprene) muaj kev tiv thaiv zoo tshaj plaws rau kev sib tsoo roj / roj tiv thaiv thiab nthuav tawm cov nplaim hluav taws kub nyhiab piv rau EPDM. Thaum ob qho tib si tswj huab cua thiab ozone zoo, CR yog qhov zoo dua thaum daim ntawv thov cuam tshuam rau cov roj av me me-raws li cov roj nplua nyeem nrog rau cov ntsiab lus atmospheric.
Q: CR roj hmab hlua puas tuaj yeem txuas rau hauv kev cai O-rings?
A: Yog. Khoom CR qaum tuaj yeem txiav kom ntev ntev thiab koom nrog siv cyanoacrylate adhesives rau kev nrawm nrawm, lossis kub-vulcanized siv cov khoom siv sib txuas rau kev ruaj khov, siab - ruaj khov zoo li qub.
Q: Yuav ua li cas koj tiv thaiv txoj hlua ntawm stretching thaum lub sij hawm installation?
A: CR roj hmab nta lub zog tensile siab thiab elastic rov qab, tab sis stretching thaum lub sij hawm installation hloov tus ntoo khaub lig-sectional txoj kab uas hla. Cov neeg tsim khoom yuav tsum txiav cov hlua me ntsis ntev dua li qhov zawj ib puag ncig thiab thawb nws tsis muaj qhov nro, tso cai rau cov khoom siv rau lub rooj zaum.
Q: Dab tsi yog tus qauv spool ntev rau kev yuav khoom ntau?
A: Standard spool lengths li ntawm 50 meters mus rau 250 meters nyob ntawm seb txoj kab uas hla. Kev cai coil ntev los yog txiav - mus rau - ntev daim tuaj yeem teev tau thaum txiav txim tso rau kom haum cov kab sib dhos.
Q: Puas yog Daim Ntawv Qhia Txog Cov Khoom Siv (MTR) muaj rau txhua qhov khoom xa tuaj?
A: Yog. Txhua qhov ntau lawm tau kuaj xyuas cov cuab yeej ntawm lub cev, thiab cov MTRs sib thooj uas qhia txog durometer, lub zog tensile, thiab elongation muaj nyob rau ntawm kev thov ua ntej lossis tom qab xa khoom.
Q: Dab tsi yog qhov kev pom zoo khaws cia kom ua kom lub neej ntev tshaj plaws?
A: Khaws cov spools hauv qhov chaw txias, qhuav (15 ° C mus rau 25 ° C) kom deb ntawm tshav ntuj ncaj qha, ozone qhov chaw (xws li lub tshuab hluav taws xob), thiab teeb pom kev zoo fluorescent los tiv thaiv qhov degradation ntxov ntxov.
