Rau kev tsim cov khau zoo, siv ntau yam khoom sib txuas. Cov txheej txheem ntawm ib txhij stitching thiab gluing prolongs lub neej kev pab cuam ntawm cov khoom. Nairite kua nplaum yog ib qho ntawm cov khoom siv txhim khu kev qha thiab ntau yam, uas feem ntau yog siv rau kev tsim thiab kho cov khau.
Ntse
Cov tshuaj no yog siv los ua cov ntaub ntawv xws li tawv, roj hmab, ua npuas ncauj roj hmab, ntoo, yas thiab ntaub.

Nairite kua nplaum muaj ntau yam khoom muaj txiaj ntsig:
- Siab thermal kuj thiab lub zog. Tsuas yog cov tshuaj lom neeg tsawg tau pom nyob rau hauv cov muaj pes tsawg leeg. Chloroprene roj hmab resin yog cov khoom tseem ceeb, nws kuj muaj cov khoom siv hluavtaws, cov kuab tshuaj tsis muaj zog thiab cov thermal vulcanizers. Nws yog ua tsaug rau cov khoom no uas cov kua nplaum yog qhov zoo.
- Nws muaj peev xwm tiv taus cov dej noo, acids thiab roj av. Nkawm khau uas siv cov kua nplaum nairite yuav ua haujlwm tau ntev txawm tias nyob hauv qhov xwm txheej tsis zoo (los nag, daus, cua, te, thiab lwm yam). Lub hlws ris cia li repels dej thiab tsis tso cai rau nws absorbed. Thiab yog li ko taw yuav tsis ntub, tsis hais huab cua. Ntau tus neeg tsim khau kho cov seams nrog cov kua nplaum, uas ua rau cov khoom sib txuas thiab tiv thaiv kom tsis txhob ya raws ntawm cov khoom. Nws yog siv los kho lub nkoj roj hmab, lub tsho dhia dej thiab lub tsheb tub.
- Kev sib txuas tseem hloov tau txawm tias qhov kub thiab txias. Ib lub seam kho nrog cov tshuaj no khaws cov plasticity nyob rau hauv tej huab cua thiab tsis cia cov khoom tawg.
- Cov sib tov yog yooj yim heev rau siv. Nws muaj ob txoj kev siv: kub thiab txias. Ob leeg muaj kev ntseeg siab, tab sis qhov txias txias yog yooj yim me ntsis, vim cov kub yuav tsum tau tshwj xeebtools.
- Cov nplaum nplaum zoo. Cov nplaum muab cov adhesion zoo txawm tias ntawm cov khoom ntxeem tau.
- Tsis lwj mus ntev. Tsis poob nws qhov zoo txawm tias qhib (tab sis tsis pub tshaj 65 feeb).
Applications
Raws li tau hais lawm, nairite kua nplaum tuaj yeem siv tau ob txoj hauv kev.
Hot:
- Thawj theem yog kev npaj ua haujlwm, uas suav nrog kev ntxuav qhov chaw ntawm plua plav thiab av. Tom qab ntawd, nws yuav tsum tau degreased nrog cawv tov thiab qhuav.
- Thov kua nplaum. Thawj txheej yuav tsum yog nyias. Tom qab 15 feeb, koj yuav tsum tau thov ib tug thib ob. Tom qab ntawd, cov khoom yog qhuav nyob rau hauv ib tug ventilated chav tsev los yog nyob rau hauv txoj kev rau 35-45 feeb ntawm ib tug kub ntawm +20 ° C.
- Ua kom sov. Cov theem no suav nrog cua sov ntawm qhov chaw mus rau qhov kub txog li 100 ° C. Tom qab ntawd, cov khoom yuav tsum tau ua tiav yuav tsum tau nias kom nruj rau ib leeg.
- Theem kawg. Cov khoom yuav tsum tau tso tseg rau 6 teev, tom qab ntawd lawv tuaj yeem siv tau.
Txoj kev txias yog tsim rau cov khoom siv uas tsis muaj qhov zoo ntawm cov khoom siv hluav taws xob: polymers, foam rubber lossis cardboard:
- Thawj theem yog kev tu cov khoom.
- Thov kua nplaum. Nairite kua nplaum yog siv rau saum npoo ntawm txheej nyias, tom qab ntawd lawv yuav tsum tau qhuav li 10 feeb ntawm qhov kub ntawm qhov tsawg kawg +22 ° C.
- Kev cog qoob loo. Nias ntawm qhov chaw ua ke thiab tuav 5-8 feeb.
- Tom qab ntawd lawv yuav tsum tau tso rau hauv qhov chaw ncaj nraim rau 24 teev. Ua tiav.
Storage rules
Khaws cov sib tov rau hauv lub thawv qub, nws tseem ceeb heev kom tsis txhob ua rau nws puas. Lub sijhawm lav - tsis pub ntau tshaj 1 xyoos ntawm qhov kub ntawm +6 txog +22 degrees kom deb ntawm cov nplaim taws qhib. Nairite khau khiab tuaj yeem ua kom tuab txawm tias tag nrho cov kev cai ua raws, tab sis qhov no tsis txaus ntshai. Nws tuaj yeem diluted nrog ethyl acetate thiab siab octane roj av. Cov muaj pes tsawg leeg yog npaj yooj yim, koj yuav tsum sib tov kua nplaum thiab cov kuab tshuaj nyob rau hauv sib npaug proportions. Qhov tseem ceeb tshaj plaws yog maj mam ncuav rau hauv cov kua nplaum sib tov thiab do kom huv si.
Thaum ua ntawv thov, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov sib tov yog flammable. Kev ua hauj lwm yuav tsum tau nqa tawm kom deb ntawm qhov qhib nplaim taws; txwv tsis pub haus luam yeeb ze ntawm qhov qhib cov kua dej. Nairite kua nplaum tsuas muaj cov tshuaj lom neeg tsawg, tab sis koj yuav tsum ua haujlwm nrog nws tsuas yog hauv cov tsev uas muaj cua zoo xwb.
Yog tias cov nplaum raug thauj ntawm qhov kub thiab txias, qhov viscosity nce ntxiv. Txawm li cas los xij, qhov no tuaj yeem kho tau los ntawm kev tso nws rau ob peb teev hauv lub tsev sov. Tom qab ntawd, nws cov txiaj ntsig tau rov qab los.
