Vim li cas vim li cas yooj ywm cable ua nyuaj nyob rau hauv ib tug tsawg kub ib puag ncig:
1. Cov khoom siv qis dua: Txhawm rau kom txo cov nqi ntawm cov cable, qee cov tub lag luam muab cov ntaub ntawv qis dua. Thaum qhov kub tshaj qhov ntsuas kub uas cov khoom tso tawm, nws yuav cuam tshuam ncaj qha rau cov hloov molecular ntawm cov khoom ntaws, thiab saum npoo ntawm lub tsho yuav hnov nyuaj rau qhov kov.
2. Kev pabcuam lub neej: Cov kev pab cuam lub neej ntawm lub pob hluav taws xob hloov tau yog nyob ntawm qhov zoo ntawm cov cable thiab qhov chaw ib puag ncig uas txuas lub cable. Lub laj kab yog tsuas yog rwb thaiv los ntawm ib qho hnab riam sab nraud. Tom qab lub sijhawm ntev, nws yuav xeb los ntawm kev txhim kho cov pa roj, thiab kev ua haujlwm rwb thaiv tsev yuav maj mam poob qis. Nws yuav maj mam muaj hnub nyoog thiab dhau los ua tawv, dhau los ua nkig lossis poob tawm, thiab tom qab ntawd nws yuav tsis muaj kab thaiv.
3. Hauv qhov no, txoj hlua hluav taws xob hloov kho yuav tawg ncaj qha nyob rau hauv kev cuam tshuam ntawm sab nraud quab yuam. Yog tias qhov ntsuas kub tseem nce qis, nws yuav ncaj qha ua rau lub cable tawg. Feem ntau, cov khoom siv ntawm cov tsho zoo li no yog PVC, uas muaj qhov tsis zoo rau cov ib puag ncig. Thaum twg nws nyuaj, nws yuav muaj qhov cuam tshuam rau tag nrho cable hloov tau.
Hais txog qhov tseeb tias cov kab hluav taws xob hloov pauv yuav tawv heev thaum qhov kub tsawg kawg, qhov laj thawj tseem ceeb yog cov khoom siv ntawm lub tsho. Feem ntau ntawm cov ntaub ntawv siv rau lub tsho ntawm cov xov hloov pauv tau raug xaiv raws li cov neeg siv khoom ib puag ncig. Cov hlua hluav taws xob feem ntau hloov pauv ntawm -30 ° thiab -80 °, Qhov ntsuas kub hloov nyob rau hauv qhov no yuav tsis cuam tshuam rau nws qhov kev ua tau zoo.
