Ntim khoom siv khoom siv | Yuav Ua Li Cas Xaiv Cov Khoom Zoo Yas Hose Khoom

Cov kev xaiv thiab cov ntaub ntawv zoo yog tus yuam sij los ua kom cov hoses zoo, uas yuav cuam tshuam ncaj qha rau kev ua haujlwm thiab siv sijhawm kawg. Cov ntaub ntawv ntawm cov yas qhwv ntsej muag suav nrog polyethylene (rau raj cev thiab lub taub hau yas), pennepatch (roj hmab, cov khoom siv ntawm cov khoom siv yuav cuam tshuam ncaj qha rau qhov zoo ntawm cov hose. Txawm li cas los xij, cov ntaub ntawv xaiv kuj nyob ntawm cov yam ntxwv xws li kev nyiam huv, dej vaper, dej paug, tshuaj tsw qab.

Kev xaiv cov kav dej: Ua ntej, cov ntaub ntawv siv yuav tsum ua kom tau raws li cov qauv kev nyiam tu, thiab cov tshuaj tua kab mob hnyav thiab cov tshuaj fluorescent yuav tsum tau tswj hwm nyob hauv cov ntau yam. Piv txwv li, rau Hoses tau xa tawm mus rau Tebchaws Meskas, Polyethylene (PE) thiab polypropylene (PP) siv yuav tsum ua kom tau raws li cov khoom noj thiab tshuaj (FDA) tus qauv 21cf117.1520.

Cov tuam txhab txheej txheem: Yog tias cov ntsiab lus ntawm kev ntim ntawm cov cuab yeej siv txhua hnub) lossis cov tshuaj tsw qab yog cov roj uas tsis yooj yim (xws li qee cov roj, acids, ntsev, ntsev, ntsev, ntsev, ntsev, ntsev, ntsev, ntsev thiab Lwm yam tshuaj kho corrosive), tsib-txheej co-extruded yas yuav tsum tau siv nyob rau lub sijhawm no. Vim tias cov oxygen permeability ntawm tsib-txheej co-extruded raj-exhenenene / Adhesive Resineability ntawm cov leeg polyethylene ib qho-txheej raj yog 150-3 teev. Nyob rau hauv ib lub sij hawm ntawm lub sij hawm ntawm lub sijhawm, qhov hnyav poob ntawm cov raj-extruded uas muaj ethanol yog kaum ob lub sij hawm qis dua li ntawm ib qho-txheej raj. Tsis tas li ntawd, Evoh yog ethylene-vinyl cawv copolymer nrog cov hluav taws xob zoo heev thiab cov tshuaj tsw qab (cov lej tuab ntawm 15-20 microns yog qhov zoo tagnrho).

Cov khoom siv tawv tawv: Cov tuam txhab siv siv txhua yam rau cov cai sib txawv rau lub ntsws ntawm Hoses, yog li yuav ua li cas thiaj li tau txais cov tawv tawv? Cov polyethylene feem ntau siv nyob rau hauv hoses yog mas tsawg-density polyethylene, high-ntom polyethylene, thiab linear tsawg-ceev polyethylene. Ntawm lawv, cov tawv nqaij txhav ntawm cov polyethylene zoo dua li qhov kev xav ntawm cov polyethylene, yog li cov kev xav tau ntawm cov polyethylene / qis-ntom polyethylene.

Cov Khoom Siv Tshuaj Tiv Thaiv: Cov Polyethylene muaj cov tshuaj zoo dua li cov roj polyethylene tsawg.

Huab cua tiv thaiv: los tswj cov khoom lag luam luv luv lossis kev ntxhov siab ib puag ncig, ib puag ncig kev nyuaj siab, cov tshuaj tsw qab), tshuaj tsw qab, muaj cov khoom xyaw uas xav tau yuav tsum tau txiav txim siab.

Kev xaiv ntawm Masterbatch: masterbatch ua lub luag haujlwm tseem ceeb hauv kev tswj hwm zoo ntawm kev tswj hwm ntawm cov hose. Yog li ntawd, thaum xaiv Masterbatch, tus neeg siv tuam txhab yuav tsum txiav txim siab seb nws puas muaj qhov zoo dispersibility, kev pom thiab hluav taws xob tsis kam thiab cov khoom tiv thaiv. Ntawm lawv, cov khoom tiv thaiv ntawm cov masterbatch yog qhov tshwj xeeb tshaj yog thaum siv cov hose. Yog tias cov masterbatch yog tsis sib xws nrog cov khoom, cov xim ntawm masterbatch yuav tsiv mus rau cov khoom, thiab cov txim yuav loj heev. Yog li, cov tuam txhab siv tshuaj txhua hnub yuav tsum kuaj qhov ruaj khov ntawm cov khoom lag luam tshiab thiab cov hoses (kev ntsuam xyuas kom ceev ceev raws li cov xwm txheej).

Hom varnish thiab lawv cov yam ntxwv zoo: cov kua roj vanish siv rau hauv UV hom thiab tuaj yeem muab faib ua kev ci ntsa iab thiab matte nto nyob rau hauv cov nqe lus ntawm tsos. Cov kua roj vanish tsis tsuas yog muab qhov pom tau zoo nkauj, tab sis kuj tiv thaiv cov ntsiab lus thiab muaj qee yam cuam tshuam ntawm kev thaiv cov pa, dej ntawm dej thiab cov tshuaj tsw. Feem ntau hais lus, kub-qhuav varnish muaj zoo adchesion mus txuas kub stamping thiab siv-screen luam ntawv, thaum UV varnish muaj cov gloss zoo dua. Cov tuam txhab niaj hnub xaiv tau tuaj yeem xaiv cov kua roj hmab uas tsim nyog raws li cov yam ntxwv ntawm lawv cov khoom. Tsis tas li ntawd, cov tshuaj varnish yuav tsum muaj cov nplaum zoo nkauj, folding saum npoo tsis muaj pitting, hnav tsis kam, corrosion tsis kam, thiab tsis muaj kev tiv thaiv thaum lub sijhawm khaws cia.

Yuav tsum muaj rau lub raj raj nruab / raj taub hau / raj taub hau: 1. Cov raj ntawm lub cev uas yuav tsum yog, tsis muaj nqaij ntuag, khawb, tej ntshav, lossis shrinkage deformation. Lub cev raj yuav tsum ncaj thiab tsis khoov duav. Lub raj raj phab ntsa tuab yuav tsum tau sib dhos. Lub raj raj phab ntsa thickness, raj ntev, thiab cov taub no ua haujlwm yuav tsum nyob hauv cov kab ke tshwj xeeb;

2. Lub raj raj taub hau thiab raj lub cev ntawm lub hose yuav tsum tau yooj yim txuas, txoj kab kev sib txuas yuav tsum tau huv thiab zoo nkauj, thiab qhov dav yuav tsum yog khaub ncaws hnav. Yuav tsum tsis txhob ua lub taub hau raj taub hau tom qab kev sib txuas; 3. Lub raj raj taub hau thiab cov raj raj raj yuav tsum phim, ntsia hlau rau hauv thiab tsis muaj dej nyob hauv cov raj thiab cov npog;

Kev luam tawm cov kev xav tau: kev ua haujlwm hose feem ntau siv lithogrocic offeSet printer (uas feem ntau yuav tsum tau ua kom muaj zog adhesion thiab kev tawm tsam kom muaj zog. Cov xim luam ntawv yuav tsum tau nyob rau hauv qhov tob tshwj xeeb, txoj haujlwm dhau los yuav tsum yog li ntawd, kev sib txawv yuav tsum tsis pub dhau 0.2 hli, thiab cov ntawv yuav tsum ua kom tiav thiab meej.

Yuav tsum muaj rau lub kaus mom yas: lub kaus mom feem ntau yog ua los ntawm polypropylene (pp) txhaj tshuaj molding. High-zoo lub kaus mom yuav tsum tsis muaj qhov tseeb shrinkage kab thiab flashing, du pwm cov kab, thiab du nrog lub taub hau raj. Lawv yuav tsum tsis txhob ua kev puas tsuaj xws li xws li brittle cracks los yog tawg thaum siv sijhawm. Piv txwv li, thaum lub zog qhib yog nyob hauv ntau qhov, cov flip cap yuav tsum muaj peev xwm tiv taus ntau tshaj li 300 daim quav tsis muaj tawg.
