Plastic screws, tseem hu ua yas screws. Feem ntau siv yas screws nyob rau hauv Tuam Tshoj yog ua los ntawm kub-soluble txhaj. Lawv tau muab faib raws li cov ntaub ntawv tseem ceeb: muaj nylon PA66 screws, PP screws, PVC screws, PE screws, thiab lwm yam., txhua yam khoom siv yog txawv, yog li qhov kev thov kuj muaj qhov kev thov. qhov txawv.
Txij li thaum daim ntawv thov loj ntawm cov khoom yas hauv kev lag luam thiab lub neej nyob rau xyoo 1970, cov khoom yas tau dhau los ua ib ceg tseem ceeb ntawm kev lag luam petrochemical thiab siv ntau yam kev siv. Piv nrog cov tsoos hlau screws, yas screws muaj kev ua tau zoo hauv ntau txoj hauv kev.
Raws li hom ntsia hlau taub hau, muaj cov ntsia hlau, ntsia hlau, hexagonal screws, screws, thiab lwm yam. Hexagonal screws muaj xws li sab nrauv hexagonal screws, sab hauv hexagonal screws, thiab sab nrauv hexagonal screws feem ntau siv bolts. Muaj ntau dua A-theem thiab B-qib hexagonal, thiab cov kev cai ntawm kev sib dhos raug siab, thiab lawv muaj kev cuam tshuam loj heev. C -Class hexagonal yog siv rau lub sijhawm uas qhov chaw ntxhib thiab qhov sib dhos tsis yog siab. Feem ntau, nws yog ib qho zoo tib yam xov ntawm cov hniav zoo. Sab nrauv hexagonal screws nyob ib ncig ntawm cov xov zoo tib yam ntawm lub voj voog ntawm lub voj voog zoo dua. Nws yog tsuas yog siv rau lub ntees ntawm nyias-walled qhov chaw los yog tej yam, kev co los yog kev hloov load.
Qhov zoo ntawm cov yas screws:
(1) Muab piv nrog cov hlau zoo tib yam, qhov zoo tshaj plaws ntawm cov ntsia hlau yas yog tias nws cov rwb thaiv tsev ua tau zoo thiab tsis ua hluav taws xob.
(2) Tsis tas li ntawd, vim tias tsis yog-hlau raug tsim, teeb liab cuam tshuam xws li vortex yuav tsis tshwm sim nyob rau hauv kev cuam tshuam ntawm tam sim no los yog lwm yam hluav taws xob teeb liab, thiab nws cov anti-interference yog tsim rau kev sib txuas lus thiab lwm yam lag luam.
(3) Cov ntsia hlau yas yog ntau cov kua qaub-resistant thiab alkaline. Qhov zoo tshaj plaws PVDF screws yog ua raws li polypropylene. Ob leeg muaj zog acid thiab alkali tsis kam. Piv nrog rau ob qho dhau los, cov nylon qwj muaj zog. Kev ua haujlwm alkali tsis zoo, yog li hauv qee qhov muaj zog acid-alkali ib puag ncig hauv qee qhov kev lag luam electroplating, yas ntsia hlau, tshwj xeeb tshaj yog PVDF screws, tau siv dav.
