I-solvents ye-organic esetyenziswa kakhulu yi-organic liquids kwi-latex paint formulations, njenge-ethylene glycol, i-propylene glycol kunye ne-film forming agents (ezifana ne-diethylene glycol butyl acetate), i-porridge hydroxyethyl cellulose inokongezwa ngokuthe ngqo kwipeyinti, emva kokongeza, qhubeka uvuselela de unyibilike ngokupheleleyo.

2, ukukrwela udonga kwiputty:

Okwangoku, i-China iphakathi kwesixeko esikhulu sokumelana namanzi, ukuchasana ne-swab ye-putty yokukhusela indalo kuye kwathathwa ngokubalulekileyo ngabantu, kwiminyaka embalwa edlulileyo, ngenxa yokuba i-putty eyenziwe ngeglue yokwakha ikhupha umonakalo wegesi ye-formaldehyde kwimpilo yabantu, isakhiwo. iglu yenziwe nge-polyvinyl alcohol kunye ne-formaldehyde acetal reaction. Ngoko ke lo mbandela ngokuthe ngcembe upheliswe ngabantu, kwaye ukutshintshwa kwesi sixhobo yi-cellulose ether uchungechunge lweemveliso, oko kukuthi, uphuhliso lwezixhobo zokwakha ukhuseleko lokusingqongileyo, i-cellulose yodwa uhlobo lwezinto ezikhoyo ngoku.

Kwiputty enganyangekiyo emanzini yahlulwe yaba yiputty eyomileyo kunye ne-putty paste iindidi ezimbini, iintlobo ezimbini ze-putty zikhetha iindidi ezimbini ze-methyl cellulose kunye ne-hydroxypropyl methyl, ukucaciswa kwe-viscosity ngokubanzi ku-3000-60000cps phakathi kweyona nto ifanelekileyo, kwindima ephambili i-cellulose kwi-putty kukugcinwa kwamanzi, ukudibanisa, ukuthambisa kunye nezinye iziphumo.

Ngenxa yokuba i-putty formula yomenzi ngamnye ayifani, ezinye ziyi-calcium engwevu, i-calcium ekhanyayo, i-samente emhlophe, ezinye ziyi-gypsum powder, i-calcium engwevu, i-calcium ekhanyayo, njl. azifani, inani eliqhelekileyo lokongezwa ngu-2 ‰-3‰ okanye njalo.

Kudonga oluvuthelayo ludikwe kukwakhiwa kwabantwana, isiseko sodonga sinokufunxa okuthile (udonga lwezitena lomgangatho we-bibulous lwaluyi-13%, ikhonkrithi yi-3-5%), idityaniswa nokuphuma komphunga kwihlabathi langaphandle, ke ukuba uyakruquka ngumntwana. ukulahleka kwamanzi ngokukhawuleza, kuya kukhokelela ekuqhekekeni okanye into efana ne-pollen, ukwenzela ukuba amandla e-putty abe buthathaka, ngoko ke, emva kokujoyina i-cellulose ether iya kusombulula le ngxaki. Kodwa umgangatho wezinto zokuzalisa, ngakumbi umgangatho we-gray calcium nawo ubaluleke kakhulu. Ngenxa ye-viscosity ephezulu ye-cellulose, iphinda ikhulise i-buoyancy ye-putty, kwaye igweme i-phenomenon yokuhamba okujingayo ekwakhiweni, kwaye ikhululekile kwaye isindisa umsebenzi emva kokukhuhla.

Kwi-powder putty, i-cellulose ether kufuneka yongezwe ngokufanelekileyo kwindawo yefektri, ukuveliswa kwayo, ukusetyenziswa kwayo kukulungele ngakumbi, izinto zokuzalisa kunye ne-powder eyomileyo encedisayo inokuxutywa ngokulinganayo, ukwakhiwa kukulungele ngakumbi, ukuhanjiswa kwamanzi kwindawo, kungakanani na.

Kwi-concrete mortar, ngokwenene ukuphumeza amandla okugqibela, kufuneka wenze i-cement hydration reaction ngokupheleleyo, ngokukodwa ehlotyeni, ekwakhiweni kodaka lwekhonkrithi ilahleko yamanzi ngokukhawuleza, amanyathelo afakwe ngokupheleleyo emanzini okunyanga, le ndlela yinkcitho yobutyebi bamanzi kwaye ukusebenza okungahambi kakuhle, isitshixo siphezu komhlaba, amanzi kunye ne-hydration ayikabikho ngokupheleleyo, ngoko ke iindlela zokusombulula le ngxaki, Yongeza i-agent egcina amanzi asibhozo kwi-concrete ye-concrete ukuze ukhethe i-hydroxypropyl methyl okanye i-methyl cellulose, i-viscosity specifikation kwi-20000- 60000cps phakathi, yongeza 2% -3%. Malunga, izinga logcino lwamanzi linokunyuswa libe ngaphezu kwama-85%, kwindlela yokusetyenziswa kodaka lwekhonkrithi yomgubo owomileyo oxutywe ngokulinganayo emva kokuba umlomo ungene emanzini unokuba.

4, igypsum yepeyinti, igypsum edibeneyo, i-gypsum edibeneyo:

Ngophuhliso olukhawulezayo lweshishini lokwakha, imfuno yabantu yezinto ezintsha zokwakha nayo iyanda imihla ngemihla, ngenxa yokwanda kolwazi lwabantu ngokukhuselwa kwendalo kunye nokuphuculwa okuqhubekayo kobuchule bokwakha, iimveliso zegypsum zesamente ziye zakhula ngokukhawuleza. Okwangoku ezona mpahla ziqhelekileyo zine-stucco gesso, i-caking gesso, iseti i-gesso, i-ejenti yokufaka iithayile zokulinda.

I-plastering i-plastering luhlobo olulungileyo lwangaphakathi eludongeni kunye nophahla lwezinto zokutyabeka, kunye nokucima udonga oluthambileyo kwaye lugudileyo, musa ukulahla umgubo kunye nebhondi yesiseko ngokuqinileyo, akukho nto iqhekezayo, kwaye inomsebenzi wokuthintela umlilo; I-Gypsum encamathelayo luhlobo olutsha lwebhodi yokuncamathelisa ukukhanya kwebhodi, igypsum njengesiseko sezinto, kunye neentlobo ezahlukeneyo zokongeza umlomo owenziwe ngezinto ezincamathelayo, ilungele zonke iintlobo zezinto ezingaphiliyo eludongeni phakathi kwebhondi, enetyhefu engenabungozi. , incasa, amandla okuqala ngokukhawuleza ukubeka, ukudibanisa ibhodi yokwakha, ukwakhiwa kwebhloko izinto ezixhasayo; I-agent ye-Gypsum yokuzalisa i-seam yi-plate ye-gypsum phakathi kwezinto zokuzalisa i-gap kunye nodonga, ukuzaliswa kokulungiswa kwe-crack.

Ezi mveliso ze-gypsum zinoluhlu lwemisebenzi eyahlukeneyo, ngaphezu kwe-gypsum kunye neefayili ezinxulumene nazo ukuze zidlale indima, umba obalulekileyo wongeziweyo we-cellulose ether additives udlala indima ephambili. Ngenxa yokuba gesso yahlulwe babe ngaphandle gesso amanzi kunye neesenti isiqingatha gesso amanzi, ezahlukeneyo gesso yahlukile isiphumo ukusebenza imveliso, ukwandisa ngokobunzima, ukukhusela amanzi, coagulate kancinci umgangatho ogqiba gesso zokwakha. Ingxaki eqhelekileyo yezi zixhobo kukuqhekeka kwegubu elingenanto, amandla okuqala akakho, ukusombulula le ngxaki, kukukhetha uhlobo lwe-cellulose kunye ne-retarder yendlela yokusetyenziswa kwekhompawundi, kulo mba, ukhetho oluqhelekileyo lwe-methyl okanye i-hydroxypropyl methyl. 30000-60000cps, imali eyongezelelweyo yi-1.5% - 2%. Phakathi, ugxininiso lwe-cellulose kukugcina amanzi kunye nokucotha kwe-condensation lubrication.

Nangona kunjalo, kule nto ukuthembela kwi-ether ye-cellulose njengoko i-retarder ingafiki, kufuneka idibanise i-citric acid retarder emva kokusetyenziswa okuxubileyo ayiyi kuchaphazela amandla okuqala.

Izinga logcino lwamanzi ngokubanzi libhekisa kubungakanani belahleko yamanzi endalo ngokungabikho kokufunxwa kwamanzi ngaphandle. Ukuba udonga lomile, umgangatho wesiseko uthatha amanzi kunye nokunyuka kwemvelo kwenza ukuba izinto eziphathekayo zilahlekelwe ngamanzi ngokukhawuleza, kwaye kuya kubakho igubu elingenanto kunye nesiganeko sokuqhekeka.
