1.Dab tsi cuam tshuam rau kev tsim khoom?
Kev them nyiaj yug thiab kev tswj nruj: Nyob rau hauv qhov nruam siab - xim txheej txheej ntau lawm kab, steel sawb (substrate) raug mob nyob ib ncig ntawm lub hauv paus rau unwinding thiab rewinding. Cov tub ntxhais yuav tsum muaj lub zog siab heev, nruj thiab roundness. Yog hais tias lub hauv paus rigidity tsis txaus los yog eccentric, lub steel sawb yuav co los yog tsis sib xws thaum lub sij hawm ua hauj lwm.
Qhov tshwm sim: Cov txheej yuav tsis sib npaug thaum dov, cuam tshuam rau kev ci thiab kev kho. Hauv qhov xwm txheej hnyav, nws tseem tuaj yeem ua rau cov txheej txheem raug khawb ntawm cov kab ntau lawm.
2.Dab tsi cuam tshuam rau winding zoo?
Ua indentations: Inferior cores (xws li cov khoom ua los ntawm cov khoom siv rov ua dua tshiab, cov phab ntsa tuab tsis sib xws, thiab cov dents) yuav imprint lawv tus kheej qhov tsis xws luag ntawm txheej txheej ntawm cov phaj hlau sab hauv thaum rov ua dua, ua rau lub sij hawm indentations lossis pob.
Ua rau "kev sib khi": Lub siab ntawm cov hlau sawb txheej yog loj heev thaum winding. Yog hais tias cov tub ntxhais yog tawm ntawm puag ncig los yog muaj zog tsis zoo, ua rau muaj kev kub ntxhov hauv zos thiab qhov kub thiab txias, interlayer bonding yuav tshwm sim. Thaum uncoiled dua, cov txheej yuav adhered thiab torn tawm, ua rau irreparable puas. Qhov no yog ib qho teeb meem loj tshaj plaws.
3.Dab tsi yog qhov cuam tshuam rau kev thauj mus los thiab kev cia khoom?
Cov cores thiab cov rolls tiaj tus: Cov tub ntxhais uas tsis muaj zog txaus (xws li qee cov ntawv tsis zoo los yog nyias- cov yeeb nkab steel yeeb nkab) tsis tuaj yeem nqa qhov hnyav ntawm tag nrho cov yob ntawm cov hlau phaj (txog kaum ob tons) thaum lub sij hawm hoisting, tsheb thauj mus los lossis stacking, thiab yuav deform thiab vau.
Qhov tshwm sim: Tag nrho cov xim -coated yob hloov mus rau hauv lub voj voog lossis cov duab tsis zoo, ua rau nws tsis tuaj yeem ua rau lub tshuab tsis zoo. Cov npoo yuav raug tsoo hnyav thiab deformed vim qhov kev ntxhov siab tsis sib xws (feem ntau hu ua "daisy edges"), thiab cov txheej thiab substrate yuav puas. Ntau tus npoo yuav tsum tau muab txiav ua ntej siv, ua rau cov khib nyiab loj.
4.Dab tsi cuam tshuam rau kev qhib- phau ntawv siv?
Lub zog ruaj khov, tus qauv winding core yog lub hauv paus rau kev ua haujlwm du ntawm cov khoom siv niaj hnub siab - ceev unwinding. Inferior cores yuav ua rau tsis muaj qhov tsis zoo, ua rau lub sijhawm poob rau kev hloov kho, ua rau lub sijhawm tsim kho thiab cov nqi.
5.Dab tsi yog cov ntaub ntawv tseem ceeb thiab cov yam ntxwv ntawm cov tub ntxhais?
Siab -lub zog steel core (siab kev lag luam tus qauv):
Khoom siv: tshwj xeeb steel yeeb nkab, phab ntsa thickness feem ntau ntau dua los yog sib npaug rau 16 hli, los yog tuab dua.
Qhov zoo: Lub zog zoo heev, nruj, thiab roundness, thiab tuaj yeem tiv taus ntau lub zog hauv kev tsim khoom thiab kev thauj mus los. Nws yog tus qauv kev teeb tsa ntawm siab - xim txheej txheej ntau lawm kab, uas tuaj yeem ua kom ntseeg tau tias cov khoom coated raug xa mus rau cov neeg siv khoom tsis zoo rau qhov loj tshaj plaws.
Disadvantages: tus nqi siab tshaj.
Ordinary steel / hlau tub ntxhais:
Cov phab ntsa tuab yog nyias lossis cov khoom siv nruab nrab, thiab lub zog thiab deformation kuj tsis muaj zog. Qhov kev pheej hmoo siab dua thaum nqa hnyav hnyav lossis nqa tsis raug. Ib qho kev xaiv rau ntau yam khoom txheem.
Daim Ntawv / Fiberboard Cores (Low End lossis Lub Hom Phiaj Tshwj Xeeb):
Feem ntau yog siv rau lub teeb aluminium coils los yog nyias nyias steel coils, yeej tsis haum rau hnyav -lub luag haujlwm xim -coated steel coils. Nws lub zog tsis tuaj yeem dais qhov hnyav ntawm ob peb tons mus rau kaum tawm tons, thiab nws yooj yim rau kev puas tsuaj loj.
