Cov roj hmab nplaum nplaum - cov khoom siv thoob ntiaj teb … Nws tau txiav txim siab tias yog cov nplaum tshaj plaws rau ntau qhov chaw. Cov tshuaj tau nquag siv hauv kev daws teeb meem hauv tsev neeg, ntawm cov chaw tsim khoom lag luam, qhov kev sib txuas zoo ntawm cov khoom sib txawv yog qhov tseem ceeb yam tsis muaj qhov sib txawv me ntsis.
Peculiarities
KN-mastics hu ua kua nplaum . Nws yog ua los ntawm indene-coumarone resins. Ua hauv cov kaus poom, nws muaj cov homogeneous loj. Kev ruaj ntseg ntawm pawg yog ua kom ntseeg tau los ntawm cov kuab tshuaj hnyav uas muaj nyob hauv qhov muaj pes tsawg leeg. Yog tias lub thawv qhib sab laug, lawv ua kom qhuav, cov nplaum ua kom tawv, nws tsis tuaj yeem diluted rau qhov xav tau viscosity. Cov txheej txheem ntawm cov kua nplaum kuj poob lawm.
Nws tau tsim tawm raws li qhov xav tau ntawm GOST. Lub peculiarity ntawm cov kua nplaum yog nws ze rau cov khoom xyaw ntuj, tsis muaj kev phom sij rau tus neeg ua haujlwm nrog nws. Mastic tau npaj los ntawm cov khoom hauv qab no:
- roj hmab hluavtaws;
- hnyav;
- muab tub lim;
- polymer cob.
Cov roj hmab nplaum nplaum tau tsim nws tus kheej ua tus neeg sawv cev tiv thaiv tsis tau tshaj plaws rau kev koom nrog cov khoom sib txawv. Kev tsim kho thiab kho ua haujlwm yuav siv qhov chaw tsis muaj teeb meem yog tias KN siv lub tshuab ua haujlwm thaum koom nrog cov khoom sib txawv. Lawv ruaj ntseg koom nrog cov khoom txiav ntawm lub hauv paus ua ntej qib.
KN-3 kua nplaum tau tsim tshwj xeeb rau plywood, uas ua rau nws muaj peev xwm daws tau ntau yam teeb meem ntawm kev tsim kho thiab kho kom zoo nkauj nrog qhov tsawg kawg ntawm tus nqi . Cov kws tshaj lij tau ntim rau hauv cov thawv ntim hlau uas ntim tau zoo. Lawv qhov sib xws yog khov, daj-xim av rau xim dub.
Cov tshuaj ntxiv uas siv los tsim cov kua nplaum tsis tso cai rau kev tsim cov pwm thiab muaj cov kab mob tua kab mob. Cov roj hmab muab cov mastic nrog cov nplaum zoo. Fillers - plasticizers, hloov kho - muab cov yas zoo rau qhov hnyav. Cov kuab tshuaj muab cov kua nplaum rau qhov xav tau sib xws thiab viscosity.
Cov yam ntxwv ntawm cov peev nyiaj
Ntau hom kua nplaum tau raug sim ntau dua 3 xyoo lawm ntawm kev siv ua haujlwm. Nws muaj cov yam ntxwv zoo tshaj plaws:
- txhim khu kev qha lub zog;
- zoo heev adhesion;
- dej tsis kam;
- bio ruaj ntseg;
- withstands kub heev, khaws nws cov khoom.
KN-2 hom kua nplaum yog siv hauv kev tsim kho, kho, thiab ua haujlwm tiav. KN-3 mastic tau tsim nyob rau hauv daim ntawv ntawm pasty loj. Vim tias muaj cov nplaum puag hauv nws, nws ua kom ntseeg tau qhov ua tau zoo ntawm ntau yam khoom siv rau hauv pem teb screed, pob zeb ua vaj tse thiab qab nthab.
Daim ntawv thov thaj tsam
Mastics tau siv hauv pem teb, kho kom zoo nkauj, phab ntsa, vov tsev ua haujlwm. Cov roj hmab hluavtaws yooj yim thiab ntseeg tau cov kua nplaum sib txawv: cov phab ntsa ntub dej, plywood, tawv tawv, chipboard, uas tau lees paub los ntawm kev suav nrog ntxiv cov yas yas hauv cov kua nplaum . Qhov tshwm sim yog kev sib txuas tsis muaj dej tsis txaus ntseeg uas tiv taus cov tshuaj ntxhua khaub ncaws, dej, siab thiab qis. Cov yam ntxwv ntawm cov kua nplaum ua rau nws siv tau hauv cov ntawv thov sab hauv thiab sab nraum zoov.
Mastic tau tsim ua kom tiav siv. Nrog nws cov kev pab, yob, pobzeb, pem teb, cov khoom siv vov tsev muaj kev ntseeg tau txuas nrog:
- PVC linoleums nrog thiab tsis muaj lub hauv paus;
- roj hmab linoleums;
- ntsib cov vuas;
- ntaub pua plag.
Roj hmab mastic yog npaj rau tso parquet, gluing baseboards. Nws yog siv los ua kua nplaum ua ke ib feem ntawm tus kheej, tiv thaiv dej, sib khi, thiab ntim khoom. Nrog nws, phab ntsa ntsib nrog ntau yam khoom dai kom zoo nkauj. Cov kua nplaum yog suav tias yog ib puag ncig tus phooj ywg thiab kev lag luam.
Cov txheej txheem thov
Ua haujlwm nrog mastic roj hmab yuav tsum nyob hauv thaj chaw muaj cua nkag, ntawm qhov qhuav, tsis muaj av, hmoov av, roj hauv paus. Ua cov mastic kom huv ua ntej pib ua haujlwm. Tom qab ntawd, nws yog qhov yooj yim thov rau txhua qhov chaw. Pom zoo txheej - 0.3 hli … Nws raug nquahu kom siv cov kua nplaum nrog cov xim pleev xim, txhuam, ntoo spatulas. Cov ntxeem tau yuav tsum tau txheej nrog 2 txheej nrog so ib hnub. Qhov khov khov ua rau muaj qhov khoob ntawm qhov uas yuav tsum tau ua ke.
Nws yog ib qho tseem ceeb yuav tsum coj mus rau hauv tus account tias KN mastic yog cov nplaim hluav taws thiab tawg heev. Vim li no, cov hlau tsis tuaj yeem siv los ua mastic: lawv muaj peev xwm txiav cov txim taws, ua rau muaj hluav taws kub.
