Nrog rau txoj kev loj hlob ntawm tib neeg, muaj ntau thiab ntau lub tsev, thiab kev ua si ntawm cov xov hlau thiab cables kuj nce. Muaj ntau hom xov hlau thiab cables. Rubber sheathed cables yog siv dav hauv ntau yam khoom siv hluav taws xob, xws li cov khoom siv hauv tsev, cov tshuab hluav taws xob, kev teeb tsa hluav taws xob thiab cov xov tooj ntawm tes rau cov khoom siv. Tib lub sijhawm tuaj yeem siv rau hauv tsev lossis sab nraum zoov ib puag ncig. Raws li cov neeg kho tshuab sab nraud quab yuam ntawm lub cable, cov khoom tsim tau muab faib ua peb pawg: lub teeb, nruab nrab thiab hnyav. Kuj tseem muaj kev sib koom ua ke zoo hauv ntu.
Kev tswj ntawm tooj liab pas nrig txheej txheem
Kev kos duab ntawm 0.4mm monofilament feem ntau yog ua los ntawm tooj liab loj kos duab tshuab thiab nruab nrab daim duab tshuab uas tau ua tiav tiav, thiab nws yuav tsum mus dhau cov txheej txheem them nyiaj-tawm, xaim kos duab thiab annealing, cua txias, ziab, thiab xaim coj- nce. Ua ntej tshaj plaws, cov pwm tsim nyog yuav tsum raug xaiv, thiab nws yuav tsum tsis txhob me me dhau, txwv tsis pub lub lattice variation ntawm hlau tooj liab yuav raug yuam, thiab qhov kub ntawm cov hlau yuav nce sharply. Qhov thib ob, xyuas pH ntawm emulsion ua ntej pib lub tshuab kom paub meej tias nws yog cov tshuaj alkaline. Nyob rau tib lub sijhawm, cov tshuaj antioxidants yuav tsum tau ntxiv rau cov roj kos duab los ua ib zaj duab xis passivation ntawm tus neeg xyuas pib tooj liab kom tsis txhob oxidation; thaum them nyiaj, ua kom cov nyiaj them- tawm ntawm qhov nro ruaj khov thiab zoo ib yam. kev tshee ntau dhau;
Thaum lub sij hawm tus txheej txheem kos duab, tus neeg teb xov tooj yuav tsum xyuas kom meej cov dej theem kom zoo los xyuas kom meej lub uniformity ntawm annealing, thiab zam tsis txaus los yog ntau tshaj annealing; Thaum noj cov hlau, yuav tsum tsis muaj cov kua dej ntxiv rau ntawm tus neeg xyuas pib tooj liab. hloov) los xyuas kom meej monotonicity ntawm monofilament. Thaum kawg, muab khi rau nws nrog lub pob tshab yas zaj duab xis tom qab kos lub phaj hauv qab, khaws cia rau hauv ib puag ncig monotonous, thiab tos rau kev ncig, txwv tsis pub nws yuav yooj yim rau oxidize nrog cov av noo vim qhov kub ntawm cov neeg xyuas pib nto.
Copper hlau stranding (stranding) thiab insulating roj hmab, sheath roj hmab extrusion txheej txheem
Noj tooj liab twisting ua piv txwv, thaum lub sij hawm twisting txheej txheem ntawm tus neeg xyuas pib, cov hlau tooj liab lattice hloov nws cov qauv los ntawm ntau yam compression tuag. Cov txheej txheej ntawm tus neeg xyuas pib tooj liab tau yooj yim oxidized. Yog li ntawd, cov tshuaj tua kab mob antioxidant (0.3 feem pua benzotriazole dej cawv tov) tuaj yeem raug xa mus rau hauv cov hlau tooj liab nrog rau cov kav dej tso rau saum cov txheej txheem twisting. Yog tias qhov tshwm sim ntawm oxidation los yog pov tseg ntau dhau, tig lub tshuab tom qab tag nrho cov kev ua haujlwm oxidation ua tiav. Xyuas kom tseeb tias tus take-reel yog monotonous ntawm take-up qhov chaw. Tom qab cov khoom siv -reel puv puv, nws raug kaw nrog lub pob tshab yas zaj duab xis.
Kev thauj mus los, kev tshuaj xyuas thiab khaws cov tooj liab rods ua ntej nkag mus rau hauv lub Hoobkas
Cov tuam txhab cable feem ntau hauv Suav teb siv tooj liab los ua cov khoom lag luam, thiab yuav tsum xaiv cov qib siab - cov hlau tooj liab zoo, cov qauv xa khoom thauj, cov txheej txheem xa khoom thiab cov txheej txheem, cov khoom siv tooj liab tuaj xyuas yog ua raws li GB / T 3048.2 lossis cable tuam txhab lag luam. qauv. Kev khaws cia ntawm cov pas nrig tooj liab tuaj yeem npog cov pas tooj liab nrog cov ntaub yas lossis yas zaj duab xis, uas yog, txoj kev yooj yim tshaj plaws ntawm lub cev thaiv kev tiv thaiv kev sib cuag ntawm cov pas nrig tooj liab thiab cov huab cua ntub. Thaum siv cov pas nrig tooj liab hauv kev cob qhia, cov pas nrig tooj liab yuav tsum tau dov ib qho los ntawm ib qho los xyuas nrog lub qhov muag liab qab seb puas muaj blackening, thiab tswj lawv los ntawm qhov chaw tsim khoom.
