Cov hauv paus ntsiab lus thiab qhov zoo ntawm kev ua haujlwm siab vuam tshuab
Cov txheej txheem ntawm high zaus vuam tshuab (tseem hu ua lub tshuab hluav taws xob siab) feem ntau yog siv ntau yam lag luam. Piv txwv li, PVC thiab PU cov khoom lag luam yuav tsum tau txuas nrog lub tshuab ua haujlwm siab. Cov khoom lag luam feem ntau ua los ntawm kev siv lub tshuab ua haujlwm siab siv vuam vias yog tarpaulins, cov tsev pheeb suab, ceilings, cov ntawv tshaj tawm sab nraum zoov, dej txaj, nkoj txau dej, txia dej thiab cov hnab ntshav, ua kom lub nro, qauv siv conveyor, nag, thiab lwm yam.
Lub hauv paus ntsiab lus thiab qhov zoo ntawm kev siv lub tshuab loj
Lub ntsiab cai tseem ceeb ntawm kev siv lub tshuab xaim hluav taws xob loj yog kom ua hluav taws xob cua sov raws li qhov nruab nrab ntawm cov khoom siv los ua welded. Muab ib daig ntawm cov khoom nruab nrab ntawm ob lub phiaj hlau (electrodes), thiab tom qab ntawd txuas lub high-zaus voltage rau cov yas yas. Qhov tshwm sim: Cov lwg me me hauv cov khoom siv pib ua kom co, thiab cov lwg me me tau thauj mus rau qhov kub uas ua rau muaj cua sov thiab ua kom sov kom yaj. Thaum ob txheej ntawm cov ntaub ntawv dhau los ntawm qhov loj-qhov tam sim no thiab nias ua ke, ob txheej txheej ntawm cov khoom siv fuse ua ke thiab ua qhov sib txuas ntawm welded sib txuas uas tuaj yeem tiv taus qhov nro.
Qhov zoo ntawm kev siv lub tshuab xaim hluav taws xob siab heev yog lub vuam vuam nrawm nrawm: nyob rau hauv ob peb lub sijhawm, kev siv vuam hluav taws xob siab yog kho kom sov thiab sai welded los ntawm sab hauv ntawm cov khoom.
Sib piv lwm txoj hauv kev siv vuam (siv cov ntxhiab, huab cua kub lossis duab hluav taws xob) nrog kev ua haujlwm siab vuam tshuab. Qhov kub ntawm lwm txoj hau kev vuam yuav tsum tau ntxiv los ntawm sab nraud. Qhov no txhais tau hais tias tshav kub yuav tsum xub nkag rau hauv cov khoom rau yaj nws txaus tsim ib lub weld. Qhov kev pheej hmoo tseem ceeb ntawm txoj kev vuam no yog hlawv cov khaubncaws sab nraud povtseg ntawm cov khoom siv vuam, uas yog, nws yooj yim rau deform saum npoo ntawm cov khoom siv vuam.
Qee cov ntaub ntawv tsim kom muaj cua sov ntau dua li lwm cov hauv qhov chaw muaj ntau cov khoom sib nqus, yog li lawv tsim nyog rau kev siv lub tshuab ua haujlwm siab. Qhov no vim tias cov lwg me me ntawm cov khoom co co rau qee yam vim yog qhov chaw siab. Qhov no yog hu ua qhov poob ntawm cov khoom siv. Qhov ntau dua qhov poob ntawm cov khoom, qhov yooj yim dua nws yog weld cov khoom siv nrog cov khoom siv siab. Cov thermoplastics uas tshwj xeeb yooj yim rau qhov txuas, xws li PVC thiab PU; cov ntaub ntawv no tau tsim tshwj xeeb uas siv cov tshuab ua muaj zog siab vuam tshuab. Cov plastics tawv xws li PE nyuaj rau weld los ntawm kev siv txoj kev loj.
