(1) Ordinary putty yog tsim los ntawm cov hmoov dawb, me ntsis hmoov txhuv nplej siab ether thiab CMC (hydroxymethyl cellulose).Hom putty no tsis muaj adhesion thiab tsis dej-resistant.

(2) Water-resistant putty paste yog tsim los ntawm high-molecular organic teeb meem, grey calcium hmoov, ultra-fine muab tub lim thiab dej-retaining agent.Qhov no hom putty muaj zoo whiteness, siab bonding zog, dej kuj, thiab yog ib tug nruj thiab alkaline khoom.

(3) Water-resistant putty hmoov yog tsim los ntawm calcium carbonate, grey calcium hmoov, cement, Nok redispersible latex hmoov, dej-retaining agent, thiab lwm yam.

(4) emulsion-hom putty yog tsim los ntawm polymer emulsion, ultra-fine muab tub lim thiab dej-retaining tus neeg sawv cev.Hom putty no muaj cov dej ua haujlwm zoo thiab ua tau yooj yim, thiab tuaj yeem siv rau ntau yam substrates, tab sis tus nqi siab thiab nws yog cov khoom nruab nrab.

(3) Raws li lub sijhawm siv: putty rau sab hauv phab ntsa thiab putty rau sab nrauv phab ntsa.

(4) Raws li kev ua haujlwm: dej-resistant putty, elastic putty, high-elastic waterproof putty.

3. Dab tsi yog qhov zoo ntawm dej-resistant putty?

Water-resistant putty yog ib qho kev xaiv zoo tshaj plaws rau cov putty zoo tib yam.

(1) Muaj zog adhesion, siab sib txuas lub zog, qee qhov toughness thiab zoo huab cua permeability.

(2) Yuav tsis muaj pulverization tom qab raug ya raws, thiab nws muaj zog tiv thaiv dej.

(3) Thaum siv cov dej-resistant putty, phab ntsa saum npoo yuav tsis tawg, tev, lossis poob.

(4) Cov phab ntsa saum npoo siv cov dej-resistant putty muaj cov tes zoo nkauj, muag muag thiab zoo nkauj, thiab zoo nkauj zoo nkauj.

(5) Tom qab cov phab ntsa nto yog qias neeg nrog dej-resistant putty, nws tuaj yeem ncaj qha txhuam los yog txhuam nrog cov xim pleev xim sab hauv.Thiab tuaj yeem txhim kho kev ua haujlwm thiab kev pabcuam lub neej ntawm cov txheej.

(6) Thaum repainting phab ntsa sab hauv, nws tsis yog yuav tsum tau tshem tawm cov phab ntsa nto, tab sis ncaj qha pleev xim rau sab hauv phab ntsa xim.

(7) Water-resistant putty yog ib qho khoom siv rau ib puag ncig uas tsis ua rau muaj kuab paug rau huab cua sab hauv.

4. Dab tsi yog qhov tsis zoo ntawm putty zoo tib yam?

(1) Lub adhesion tsis zoo thiab lub zog sib txuas yog tsawg.Yuav kom kov yeej qhov teeb meem no, qee lub tuam txhab txhim kho tsev zoo siv tus neeg sawv cev cuam tshuam ntawm lub hauv paus.Nce tus nqi thiab nce tus txiv neej-teev.

(2) Tsis muaj zog.

(3) Pulverization yuav tshwm sim sai tom qab ntsib cov dej noo.

(4) Cracking, tev, tev thiab lwm yam tshwm sim tshwm sim hauv lub sijhawm luv luv.Tshwj xeeb tshaj yog rau cov kev kho mob ntawm lub moisturizing board ntawm lub puab phab ntsa, nws yog ib qhov nyuaj rau tshem tawm cov saum toj no tshwm sim txawm hais tias nws yog tag nrho kaw nrog ntaub.Tom qab kev tsim kho tiav, nws yuav nqa ntau yam kev kho, uas yuav ua rau tsis yooj yim rau cov neeg siv.

(5) Thaum repainting phab ntsa, thawj 821 putty yuav tsum tau muab tshem tawm, uas yog laborious thiab pollutes ib puag ncig.

(6) Qhov saum npoo tsis yog ilv txaus thiab kev ntxhib los mos tsis zoo.

5. Hauv kev sib piv, qhov zoo ntawm putty hmoov yog dab tsi?

Putty hmoov yog sib tov ntawmpolymer hmoovthiab powdery kua nplaum.Tom qab sib tov nrog dej hauv ib qho kev faib ua feem, nws tuaj yeem siv rau theem phab ntsa.Txij li thaum formaldehyde tsuas muaj nyob rau hauv gaseous los yog kua daim ntawv, piv txwv li, formaldehyde cov ntsiab lus nyob rau hauv putty hmoov yog qhov tsawg tshaj plaws los yog txawm tsis muaj nyob, uas yog ntau environmentally phooj ywg.
