Raws li koj paub, aluminium yog qhov nyuaj rau xim, qhov no yog vim qhov tseeb tias nws cov txheej yog du heev. Qhov nyuaj ntawm cov qauv saum npoo, qhov rougher nws yog, thiab qhov loj dua qhov chaw ntawm kev sib cuag nrog cov khoom. Cov yam ntxwv no yog hu ua lub zog tensile ntawm kev sib txuas. Qhov teeb meem ntawm txoj kev thov ntawm kev tiv thaiv muaj pes tsawg leeg rau saum npoo tuaj yeem daws tau ob txoj hauv kev, ib qho ntawm lawv muaj kev sib tsoo ntxhib, thaum lwm qhov yog acid etching. Txoj hauv kev zoo tshaj plaws los npaj cov lus piav qhia rau kev kho kom zoo nkauj ntxiv yog siv cov primer.

yam ntxwv VL-02

Primer rau txhuas VL-02 yog kev sib xyaw ntawm cov khoom siv hauv tsev thiab tsim khoom raws li lub xeev cov qauv. Nws muaj lub hauv paus nyob rau hauv daim ntawv ntawm zinc crown ncua kev kawm ntawv thiab ib tug acid diluent. Thawj cov khoom xyaw yog cov xim daj los tiv thaiv corrosion, ua tsaug rau cov primer tau txais qhov zoo ntawm adhesion rau qhov chaw nyuaj. Ntawm cov yam ntxwv ntxiv ntawm lub hauv paus yog cuam tshuam lub zog thiab elasticity. Raws li rau acid diluent, nwsyog ib qho cawv nyob rau hauv aqueous tov ntawm phosphoric acid. Nws tau lees tias qhov txhuas nto yuav raug etched thaum ua.

Tsim nta

Txhawm rau siv cov primer saum toj no rau txhuas, nws yuav tsum tau muab sib xyaw thiab nchuav rau hauv lub thawv uas muaj kua qaub, nws tuaj yeem yog iav lossis polyethylene ntim. Rau 4 pawg feem ntawm lub hauv paus, ib feem ntawm acidic diluent yuav tsum tau ntxiv. Qhov tshwm sim muaj pes tsawg leeg yuav tsum muaj hnub nyoog rau ib nrab ib teev, tom qab ntawd nws yuav tsum tau tov zoo. Kev nthuav tawm yog xav tau rau qhov siab tshaj plaws ntawm kev sib cais ntawm polyvinyl butyral hauv cawv puag. Nws tiv taus dej, oxygen, tab sis tsis haus cawv. Lub neej txee ntawm cov av no yog 8 teev. Qhov sib tov no yog siv rau saum npoo kom pleev xim nrog ib txheej nyias, uas tuaj yeem muaj li ntawm 6 txog 8 microns. Koj tuaj yeem siv txhuam los yog tshuaj tsuag rau qhov no. Lub sij hawm ziab yuav siv tsis pub ntau tshaj ib teev. Koj yuav tau them txog 110 rubles ib kilogram ntawm xws li ib tug muaj pes tsawg leeg.

Txoj kev ntawm primer "Nerzhaluks"

Yog tias koj xaiv primer rau txhuas, koj yuav nyiam "Nerzhaluks", uas yog acrylic nplaum sib tov rau cov hlau tsis muaj hlau thiab txhuas. Ntawm nws cov nta:

• txhim khu kev qha adhesion nrog lub tsho sab saum toj;
• dej resistant;
• weatherproof;
• nce adhesion rau hlau;
• short drying phase.

Nrog kev pab los ntawm "Nerzhaluks" nws tuaj yeem npog tsis tau tsuas yog txhuas, tab sis kuj galvanized nto,zoo li aluminium alloys. Qhov no yog ib qho tseem ceeb primer kuj yog npaj rau ferrous thiab non-ferrous hlau raws li hloov acrylic copolymer. Qhov sib tov yog siv rau kev npaj ua ntej ntawm stainless thiab carbon steel, magnesium, aluminium, galvanized thiab titanium nto. Qhov no primer rau txhuas muaj peev xwm muab adhesion lub zog ntawm cov ntaub ntawv, tsis kam mus rau dej thiab chav, roj, ntxhia roj, dej hiav txwv, kerosene, roj av thiab lwm yam khoom siv roj av. Cov sib tov kuj tseem yuav pab tau thaum cov pa phem, ntsev, cov kua qaub thiab alkalis yuav ua rau ntawm qhov chaw thaum lub sijhawm ua haujlwm. Qhov no acrylic muaj pes tsawg leeg yog siv kom tau ib qho kev tiv thaiv corrosion tiv thaiv ntawm lub hauv paus ntawm lub tsev, uas muaj xws li:

• galvanized ru tsev;
• hlau txheej;
• dome;
• hangars;
• galvanized profile;
• khoom ntawm cov tshuab thiab lwm yam khoom siv hlau.

Yuav siv li cas

Ua ntej siv cov primer "Nerzhaluks" yuav tsum sib tov zoo kom txog thaum tus. Daim ntawv thov yuav tsum tau nqa tawm ntawm qhov chaw qhuav, uas yav tas los tau ntxuav ntawm xeb, plua plav, av thiab roj. Yog hais tias xeb muaj nyob rau ntawm qhov chaw, nws yuav tsum tau muab ntxuav rau Sa 21/2 siv txoj kev abrasive moj tej tawg. Daim ntawv thov yuav yog los ntawm cov menyuam, txhuam, tsis muaj tshuaj tsuag lossis cov cuab yeej cua. Yog muajtsim nyog, cov primer tuaj yeem diluted ua haujlwm viscosity, thaum koj tuaj yeem siv cov kuab tshuaj R-648 lossis R-5A.

Tswv cua kub

Cov saum toj no txhuas lub nkoj primer yuav qhuav mus rau qib 3 hauv ib nrab ib teev, tab sis tsuas yog yog tias chav tsev kub nyob hauv 20 ° C. Tom qab ziab ntawm qhov kub ntawm 20 ° C, cov txheej txheem ntxiv ntawm cov kua roj vanish thiab cov xim tuaj yeem siv tau. Nws yog ib qho tsim nyog yuav tsum siv cov av ntawm qhov kub ntawm +5 txog +30 ° C, thaum chav tsev yuav tsum muaj cov av noo uas tsis tshaj 80%.

Kev noj haus thiab ceev faj

Ua ntej yuav ib lub primer, nws yog ib qho tseem ceeb kom paub koj tus kheej nrog kev noj ntawm cov muaj pes tsawg leeg, uas muaj peev xwm sib txawv ntawm 80 mus rau 120 g / m 2, qhov no yog qhov tseeb yog tias thickness ntawm ib txheej yog sib npaug rau qhov txwv ntawm 8 txog 15 microns. Cov kws tshaj lij qhia ua ntawv thov txog 2 txheej. Ntawm kev muag khoom koj tuaj yeem pom cov primer no, uas tau nthuav tawm hauv cov xim daj. Thaum siv cov primer no, nws yog ib qho tseem ceeb kom ceev faj. Thaum ua haujlwm sab hauv thiab tom qab lawv ua tiav, nws yog ib qho tsim nyog yuav tsum tau ua kom cua nkag mus rau hauv chav tsev, thiab nyob rau hauv tus txheej txheem ntawm kev siv cov sib tov, nws yog ib qhov tsim nyog yuav tau siv cov khoom tiv thaiv tus kheej. Tus nqi ntawm ib kilogram ntawm xws li primer yog 233 rubles.

Kev piav qhia ntawm Lub Cev 960 Ntxuav Primer

Xws li primer rau txhuas (aerosol)siv tau yooj yim dua. Piv txwv li, Lub Cev 960 Wash Primer yog muag hauv cov pob sib txawv, suav nrog hauv daim ntawv ntawm aerosol. Qhov sib tov yog cov khoom siv zoo tiv thaiv corrosion acid-kho primer, uas yog tsim los ntawm polyvinyl butyl puag. Nws yog yuav tsum tau tov nrog ib tug activator thiab yog npaj rau tag nrho thiab siv tshuaj pleev ib ce. Nrog nws, koj tuaj yeem khaws cov xeb thiab tiv thaiv kom tsis txhob kis mus ntxiv. Qhov sib tov no muaj qhov zoo ntawm adhesion nrog cov hlau tsis muaj hlau. Tom qab ua tiav cov theem ziab, nws lav qhov kev tiv thaiv corrosion ntawm qhov chaw. Cov txheej txheej dries hauv 10 feeb, tom qab ntawd lub hauv paus tsis tas yuav tsum tau sib tsoo thiab tuaj yeem pleev xim nrog ob qho khoom sib xyaw. Nrog rau cov primer no, koj tuaj yeem tiv thaiv txhuas los ntawm ntsev, noo noo, thiab tseem muab cov yam ntxwv ntawm qhov tsis kam rau atmospheric, mechanical thiab tshuaj influences.

Cov lus qhia tshwj xeeb

Lub cev 960 Txhuas Primer tuaj yeem ua cua qhuav ntawm qhov kub ntawm qhov tsawg kawg nkaus ntawm 15 ° C. Tsis txhob siv cov ntaub ntub dej ntub dej ntawm qhov sib xyaw no. Nws tsis pom zoo kom siv cov ntaub ntawv polyester rau cov av acidic, suav nrog, piv txwv li, putty. Yog hais tias txog ib teev dhau los tom qab ua tiav ntawm kev ua haujlwm, ces cov primer yuav tsum tau kho nrog cov nplaum primer, uas yuav ua rau kom qhov zoo ntawm adhesion.

Txoj kev siv

Cov saum toj no aluminium acid primer yuav tsum tau tov ua ntej siv kom txog thaum homogeneoussib xws. Cov sib tov yog tshuaj lom, yog li yuav tsum tau ceev faj. Ntawm 20 ° C, qhov saum npoo yuav ncav cuag qhov ceev ntawm 0.85 kg / l. Ib liter ntawm sib tov yuav txaus rau 10 m 2 puag, uas yog qhov tseeb yog tias lub thickness ntawm txheej txheej yog 10 microns.

Quality of alkyd enamel primer

Enamel primer rau txhuas yog kev lag luam muaj nyob rau hauv alkyd sib tov PF-115. Nws muaj qhov adhesion siab rau cov hlau, thiab tseem muaj qhov zoo ntawm kev tiv thaiv txhua yam huab cua. Tom qab ziab, roj thiab lubricants tuaj yeem cuam tshuam rau saum npoo. Cia lub sij hawm nruab nrab ntawm cov tsho tiv no kom lub ntsej muag kom qhuav tag. Yog tias cov xim tuab dhau lawm, lub sijhawm ziab yuav siv sijhawm txog 5 hnub.

Zoo kawg

Hais txog cov lus saum toj no, nws tuaj yeem sau tseg tias tsis yog VL-02 txhuas primer, tab sis kuj tseem siv tau rau lwm cov khoom siv los tiv thaiv qhov chaw tau piav qhia. Koj xaiv qhov twg yog nyob ntawm koj.
