Kev tsim khoom niaj hnub no hauv txhua qhov chaw yog nce raws cov khoom ntuj tsim. Ntau ntawm lawv muaj cov yam ntxwv tshwj xeeb. Ib qho piv txwv yog textolite - tag nrho ntuj thiab siv nyob rau ntau thaj chaw.
Dab tsi yog textolite
Textolite yog cov txheej txheem laminate uas tau txais los ntawm kub nias ntawm cov ntaub paj rwb. Cov ntaub, nyob rau hauv lem, yog impregnated nrog ib tug thermosetting binder raws li phenol-formaldehyde cob. Qee zaum polyester, phenol-formaldehyde, epoxy, polyamide, furan, silicone resins lossis thermoplastics yog siv los ua impregnation.
Txawm li cas los xij, nws ua tsaug rau daim ntaub paj rwb uas cov khoom siv no muaj lub zog compressive, muaj zog tawv thiab tiv taus cov tshuab ua haujlwm zoo: drilling, txiav lossis xuas nrig ntaus.
Tag nrho cov kev zoo no txiav txim siab qhov kev siv ntawm textolite - kev tsim khoom ntawm cov seem thauj nrog hloov khoom siv hluav taws xob thiab kho tshuab lossis ua haujlwm hauv kev txhuam.
Tsis tas li ntawd, textolite yog cov hluav taws xob zoo hluav taws xob.
Nyob rau hauv dav dav, cov yam ntxwv ntawm cov khoom no lom zem ntau nyob ntawm cov yam ntxwv ntawm cov ntaub thiab phau ntawv los ntawm cov ntawv nyeem uas ua, nrog rau cov thev naus laus zis ntawm nws cov khoom lag luam.
Hauv qhov no, qhov sib txawv yog tsim ntawm textolites, organotexolites, fiberglass laminates, asbestos laminates, carbon laminates thiab basalt laminates. Thiab cov ntaub qhwv lawv tus kheej txawv ntawm hom ntaub, tuab thiab qhov ntom saum npoo.
Cov Scopes ntawm PCB
Textolite tau pom daim ntawv thov hauv ntau qhov chaw. Piv txwv, nws yog dav siv hauv kev siv hluav taws xob thiab hluav taws xob ua khoom siv hluav taws xob insulating los yog lub tshuab cua sov.
Vim nws hnav thiab kev co tsis kam, kev sib txhuam ntu yog tsim los ntawm nws - bearings, bushings, rings, txuas, lwm yam. Qee hom PCB siv nyob rau hauv kev lag luam chemical kom ua haujlwm nrog kev tshaj tawm.
Tsis tas li ntawd, nws yog siv rau kev ua haujlwm hauv kev hloov pauv roj thiab hauv huab cua hauv qhov xwm txheej ntawm qhov tsis paub meej nyob rau hauv qhov chaw ntawm 50Hz.
Cov cav tov thiab khoom siv, qhov ntawm cov uas tau ua los ntawm PCB thiab nws lub zog, txhim kho cov khoom lag luam ntau ntxiv ntawm cov khoom lag luam.
Sib txawv ntawm cov ntawv thiab cov tub ntxhais kawm ntawv.
Ntawv textolite yog polymer tsim rau tso txheej poob siab-haum rau hauv cov khoom hluav taws xob. Nws yog ib qho muaj pes tsawg leeg ntawm paj rwb npuag nias thiab impregnated nrog ib qho qauv ntawm kev txhim kho.
Core textolite yog cov ntawv tshwj xeeb ntawm kev tso cov khoom paj rwb tib yam. Qhov txheej txheem cua no tso cai rau PCB los siv rau hauv kev siv hluav taws xob ntau.
