1. Lub hauv paus ntsiab lus ntawm kev tiv thaiv cov kua qaub thiab cov roj-tiv taus cov dej-repellent fabrics yog qhov zoo ib yam, uas yog hloov cov yam ntxwv ntawm cov ntaub fiber ntau nto los ntawm kev ua tiav. Feem ntau, cov kua dej poob rau ntawm cov khoom nto, vim yog qhov nro thiab kev sib cuam tshuam ntawm cov kua thiab cov khoom. Ua rau cov tee dej los ua ntau yam duab. Raws li pom nyob rau hauv daim duab L, thaum hu rau Angle e = lao0, cov kua tee yog nyob rau hauv cov duab ntawm cov hlaws dai, uas yog ib qho zoo tagnrho lub xeev uas tsis yog-humid, uas yog lub hom phiaj kawg ntawm kev tiv thaiv ntaub tiv thaiv cov dej tsis zoo. Txawm li cas los xij, vim tias ib txwm muaj qee qhov adhesion ntawm ob theem, qhov xwm txheej uas qhov kev sib cuag lub kaum sab xis yog sib npaug rau } so0 yeej tsis tau tshwm sim, thiab tsuas yog qee qhov kwv yees tuaj yeem tau txais feem ntau. Piv txwv li}bo0 lossis ntau dua. Thaum e = o0, uas yog, cov kua poob yog paved ntawm cov khoom nto, uas yog lub xeev txwv tias cov khoom nto ntub los ntawm cov kua poob. Feem ntau, cov ntaub tsis tiav yog nyob rau hauv lub xeev no thaum nws tiv nrog cov kua. Kev ua tiav ntawm qhov chaw ntawm cov ntaub yog ua kom qhov kev sib cuag Angle e loj npaum li qhov ua tau, kom cov kua yog ib txwm nyob hauv cov hlaws zoo nkauj ntawm cov ntaub, thiaj li ua tiav lub hom phiaj ntawm kev tsis ntub dej thiab tsis yog adhesion. 2. Kev tiv thaiv kev ua haujlwmaramid ntawv Hoobkas
(1) Cov ntaub ntawv pov thawj ua haujlwm acid thiab alkali pov thawj cov khaub ncaws ua haujlwm tau koom nrog cov neeg ua haujlwm ua kua qaub nrog cov kua qaub pov thawj cov khaub ncaws, nws yog ua los ntawm cov ntaub ntawv pov thawj acid, nyob rau hauv cov qauv yuav tsum tau raws li lub dab tshos nruj, cuff nruj thiab nruj hem, thiab tsis tuaj yeem muaj cov hnab ris ci, xws li cov hnab ris yuav tsum tau ntxiv kom npog cov kev xav tau ntau lawm. Raws li tus qauv ntawm GB12012-89 "acid pov thawj cov khaub ncaws ua haujlwm", muaj cov cim tseem ceeb hauv qab no rau kev tshuaj xyuas cov khaub ncaws ua haujlwm acid. Acid nkag mus rau lub sij hawm: yog hais txog lub sij hawm ntawm cov kua qaub nkag los ntawm qhov chaw ntawm lub pub rau sab hauv, qhia nyob rau hauv feeb.aramid ntawv HoobkasLub sijhawm ntev, qhov ua tau zoo dua. Antistatic daim ntaub, acid repellent: yog hais txog qhov tsis-adhesion kev ua tau zoo ntawm qhov chaw ntawm kev pab cuam nyob rau hauv qhov kev txiav txim ntawm cov kua qaub, qhia los ntawm cov efficiency Performance index, qhov ntau dua qhov feem pua, qhov nyuaj rau cov acid adhesion. Txo tus nqi ntawm acid leaching zog: yog hais txog qhov hloov pauv ntawm tearing zog ntawm kev pab cuam tom qab acid etching. Qhov kev hloov me me, qhov zoo dua. Thaum peb siv cov khaub ncaws ua haujlwm acid-pov thawj, peb yuav tsum xub ua tib zoo saib seb cov ntsuas kev ua haujlwm tseem ceeb ntawm daim ntawv tshuaj ntsuam xyuas tau muab los ntawm cov chaw tsim khoom ua tau raws li tus qauv yuav tsum tau ua, uas yog ib kauj ruam tseem ceeb los xyuas kom meej tias peb muaj kev nyab xeeb ua haujlwm.
(2) Anti-roj thiab dej-repellent anti-static npuag tiv thaiv khaub ncaws tiv thaiv roj thiab dej-repellent tiv thaiv khaub ncaws yog tsuas yog siv rau kev sib cuag nrog cov roj thiab dej nruab nrab ntawm kev khiav hauj lwm ib puag ncig, xws li roj, downhole thiab machining hauj lwm, nws lub ntsiab tiv thaiv ntsuas yog tiv thaiv roj thiab dej-repellent. Cov roj tsis kam yog cov roj ntxhia dawb thiab n-heptane raws li kev faib ua feem ntawm 20% thiab 80%, nws cov qhab nia yog 130 cov ntsiab lus; Raws li 70% thiab 30% piv, nws cov qhab nia yog 80 cov ntsiab lus.aramid ntawv HoobkasMuab ib lub tee ntawm cov kua sib txuam rau ntawm cov roj thiab dej tiv thaiv khaub ncaws. Tom qab 3 feeb, saib cov ntaub hauv qab ntawm cov kua dej los ntawm lub kaum sab xis 45 degree kom pom tias nws muaj kev cuam tshuam thiab ci, ces cov ntaub tsis ntub; Yog hais tias hauv qab ntawm cov ntaub darkens los yog tee kis, nws yog ntub. Tus nqi roj repellent yuav tsum tsis pub tsawg tshaj 130 ntsiab lus ua ntej ntxuav; Tom qab ntxuav rau 30 zaug, tus nqi ntawm cov roj repellent yuav tsum tsis pub tsawg tshaj 80 ntsiab lus. Cov tshuaj tiv thaiv dej yog txoj kev txau dej rau saum npoo ntawm cov ntaub, cov ntaub thiab kab rov tav ntawm 45 degree Lub kaum sab xis, cov dej ntws yog perpendicular mus rau kab rov tav txoj kev tshuaj tsuag, soj ntsuam cov qib dej ntawm qhov chaw, cov dej sib txawv Cov tshuaj tiv thaiv kev ua haujlwm ntawm cov dej muag khoom sib txawv (Daim duab 2)} cov lus piav qhia qib dej tshuaj tiv thaiv: Qib 1 - txhua qhov ntub dej ntawm qhov chaw 2 - ib nrab ntub ntawm qhov chaw, wrinkle-proof ironing daim ntaub, uas feem ntau yog hais txog qhov sib npaug ntawm ib qho me me ntawm qhov chaw ntub dej tsis sib txuas. Theem 3 - Cov dej ntub dej tsuas yog thaj chaw me me uas tsis txuas nrog. Qib 4 - tsis muaj dej ntub rau ntawm qhov chaw, tab sis muaj cov te me me ntawm cov dej ntawm qhov chaw Theem 5 - tsis muaj qhov ntub dej ntawm qhov chaw, thiab tsis muaj dej me me ntawm qhov chaw. Raws li cov txheej txheem tau piav qhia saum toj no, cov neeg siv kuj tuaj yeem ua qhov kev ntsuas kev ua haujlwm yooj yim ntawm cov khaub ncaws tiv thaiv roj thiab dej tiv thaiv cov khaub ncaws ntawm lub sijhawm zoo tib yam. Txawm hais tias qhov kev tshawb pom txhais tau tias tsis tuaj yeem ua tus qauv zoo, qhov kev tiv thaiv dav dav ntawm kev tiv thaiv cov kua qaub thiab alkali ntaub tiv thaiv cov khaub ncaws tuaj yeem raug txiav txim.
