Qhov hnyav:
Qhov hnyav ntawm cov xov hlau uas muaj cov khoom zoo yog feem ntau nyob rau hauv cov ntawv sau.Piv txwv li, Yas insulated ib qho tooj liab tub ntxhais hlau nrog ntu ntu ntawm 1.5, qhov hnyav yog 1.8-1.9kg ib 100 meter;Yas insulated ib qho tooj liab tub ntxhais hlau nrog ib feem ntawm 2.5 yog 2.8 ~ 3 kg ib 100 m;Yas insulated ib qho tooj liab tub ntxhais hlau nrog ntu ntu ntawm 4, qhov hnyav ntawm 4.1 ~ 4.2 kg ib 100 m.
Cov xov hlau tsis zoo yog qhov hnyav, tsis ntev txaus, los yog muaj ntau yam impurities hauv lawv cov cores tooj liab.
Tooj:
Tsim nyog tooj liab hlau tooj liab tub ntxhais yuav tsum yog purplish liab, ci iab, mos zoo li.Thiab cov tub ntxhais tooj liab ntawm shoddy tooj liab tub ntxhais yog violet dub, slant daj los yog slant dawb, impurity ntau, txhua yam muaj zog tsis zoo, tenacity tsis zoo, me ntsis quab yuam. yuav tawg nws, thiab feem ntau muaj qhov tshwm sim tawg hauv cov xaim hluav taws xob.
Txhawm rau kuaj xyuas, tsuas yog strip 2 cm ntawm ib kawg ntawm cov hlau thiab rub ib daim ntawv dawb rau ntawm cov tub ntxhais tooj liab.Yog tias muaj cov khoom siv dub rau ntawm daim ntawv dawb, nws txhais tau tias muaj ntau yam impurities hauv cov tub ntxhais tooj liab.
Tsis tas li ntawd, txheej rwb thaiv tsev ntawm cov xov hlau cuav zoo li tuab, tab sis feem ntau yog ua los ntawm cov yas siv dua tshiab.Nyob rau tib lub sijhawm, txheej rwb thaiv tsev yuav muaj hnub nyoog thiab xau hluav taws xob.
Chaw tsim tshuaj paus:
Cov xov hlau cuav feem ntau tsis muaj lub npe tsim khoom, tsis muaj chaw nyob, tsis muaj daim ntawv tso cai kev noj qab haus huv ntau lawm.Tab sis nws kuj muaj cov cim keeb kwm tsis meej, xws li ua nyob rau hauv Suav teb, ua nyob rau hauv Suav xeev lossis nroog.Qhov no yog qhov sib npaug rau cov keeb kwm tsis muaj cim.
Nqe:
Fake thiab shoddy hlau cov nqi ntau lawm yog tsawg, yog li ntawd, cov neeg muag khoom nyob rau hauv kev muag khoom, feem ntau pheej yig thiab zoo zoo rau lub npog ntawm kev muag khoom tsawg, ua rau cov neeg dag.
Kuaj:
Peb tuaj yeem nqa lub taub hau hlau los khoov dua nrog tes, yog tias nws hnov ntxhiab, zoo qaug zog lub zog, yas los yog roj hmab xav tias elastic thiab tsis tawg ntawm cov hlau insulator, ces nws zoo heev.
Saib ntawm qhov tseem ceeb:
Saib yog tias cov tub ntxhais nyob hauv nruab nrab ntawm cov txheej txheem rwb thaiv tsev.Tsis yog qhov nruab nrab yog vim cov thev naus laus zis tsawg thiab ua rau cov tub ntxhais sib txawv ntawm qhov tshwm sim, hauv kev siv yog tias lub zog me me tab sis kuj tuaj yeem ua neej nyob kaj siab lug, thaum lub zog siv hluav taws xob loj, sab thinner zoo li yuav tawg los ntawm qhov tam sim no.
Saib ntawm qhov ntev thiab cov tub ntxhais thickness:
Txhawm rau saib seb qhov ntev thiab cov tub ntxhais tuab tau raug cuam tshuam li cas.Raws li cov qauv tsim, qhov yuam kev ntawm cov xaim ntev yuav tsum tsis pub tshaj 5%, thiab qhov yuam kev ntawm kab kab kab yuav tsum tsis pub tshaj 0.02%. Feem ntau cov tshwm sim uas luv luv ntsuas nyob rau hauv ntev thiab falsification nyob rau hauv seem.Piv txwv li, ib kab nrog ib tug ntoo khaub lig-section ntawm 6 square millimeters yog tiag tiag tsuas yog 4.5 mm square.
Saib ntawm lub ntim:
Cov hlau zoo yog feem ntau ua kom zoo nkauj dua, xav tias zoo nkauj heev.National standard hlau 1.5 mus rau 6 ca hlau rwb thaiv tsev thickness yuav tsum yog 0.7 hli, tuab heev yog non-standard, sib xws rau nws cov tub ntxhais yog yeej tsis tsim nyog.Line tawv koj tuaj yeem rub tawv, tsis yooj yim los tsim kua muag yog lub teb chaws tus qauv.Koj tuaj yeem yuam kom rub ib kab ntawm daim tawv nqaij, tsis yooj yim los tsim kua muag yog lub teb chaws tus qauv.
Ceev faj:
Yog tias qhov hluav taws kub tua tsis pub dhau 5s tom qab hluav taws tawm, cov uas muaj qee yam nplaim taws ua haujlwm yog lub teb chaws tus qauv.
