Organic silicon waterproofing cov neeg sawv cev muaj cov waterproof zoo, pob zeb, thiab lwm yam. Thaum siv rau hauv lub microporous phab ntsa thiab daim ntawv a Hydrophobic zaj duab xis nyob rau saum npoo lossis sab hauv ntawm cov substrate kom ua tiav lub hom phiaj ntawm waterproofing. Muaj ntau ntau yam ntawm cov organic silicon waterproofing cov neeg sawv cev ntawm kev ua lag luam, thiab qhov cuam tshuam ntawm kev siv sib txawv. Lawv feem ntau muab faib ua ob peb pawg: cawv cawv: silicone cob, silicone cob, silane, thiab organic silicon emulsion.
Ib tug. Methylsiliconate
MethylsilicanATate yog thawj tiam ntawm cov neeg sawv cev dej silicone dej. Nws yog cov khoom siv tsis muaj dej. Thaum siv, nws tuaj yeem hnov cov tshuaj nrog rau saum npoo ntawm cov txheej txheem ntawm cov pa roj carbon dioxide thiab dej hauv huab cua los ua cov pa hydrophobic polymethylsiloxane zaj duab xis. Qhov kev tsim kho no nrog tus qauv mesh tuaj yeem thaiv cov hws hauv lub cug cug, txhim kho nws qhov tsis haum, yog li ua si lub luag haujlwm tsis muaj dej. Txawm li cas los xij, nws yuav tsim cov hmoov dawb dawb ntawm cov npoo ntawm substrate, lossis yellow vim muaj zog heev alkalinity, yog li cuam tshuam rau lub tsev morphology dhau los ntawm lub tsev. Tsis tas li ntawd, methylsiliconate tseem yuav tsim cov seemalol hauv qab cov kev mob alkaline muaj zog thiab yaj hauv dej thiab poob nws cov dej tsis muaj tseeb.
Tus neeg sawv cev tsis muaj dej muaj qhov zoo ntawm cov tsis muaj tshuaj lom, tsis muaj kuab, tsis muaj nplaim taws, tsis muaj huab cua tsis kam, thiab tsis muaj xeb rau cov hlau tuav; Nws tseem muaj micro-expansion nyhuv, uas tuaj yeem them rau cov shrinkage ntawm cug cug thiab qhob Nws tuaj yeem tsim tsa ntawm cov chaw ntub dej tsis cuam tshuam rau kev sib raug zoo txheej ntawm cov txheej txheem dej tsis huv, thiab kev ua haujlwm tsim kho yog qhov yooj yim thiab hloov tau; Nws yog qhov yooj yim thauj, muaj kev nyab xeeb los tsim, thiab tus nqi qis.
Ob. Silicone resin
Tam sim no, cov nquag tivthaiv ntawm cov khoom siv dej silicone waterproofing hauv kev ua lag luam hauv tsev yog methyl silicone resin. Hauv kev lag luam ntau lawm, nws tau npaj los ntawm hydrolysis thiab hws ntawm methyltrichhlorane hauv organic kuab tshuaj. Nws kuj tseem tuaj yeem npaj los ntawm methyltrialkoxsilane. Cov txheej txheem tshwj xeeb yog rau hydrolyze methyltrialkoxoxsilane nyob rau hauv muaj cov dej ntau dhau thiab kab hydrochloric acid. Thaum pib ntawm cov tshuaj tiv thaiv, lub system yog ob-theem, thiab raws li cov tshuaj tiv thaiv ua, nws hloov dua siab tshiab rau hauv homogeneous theem. Tom qab feem ntau ntawm cov cawv thiab dej yog evaporated, ib qho tsis muaj xim thiab pob tshab Methyles Silicone Resin Soluble hauv cawv tau.
Silicone resin muaj qhov kub siab thiab tsis kam, kev tiv thaiv hydrophobicity thiab huab cua permeability, tsis muaj cua thiab tsis muaj tshuaj lom thiab tsis ntseeg. Nws suav hais tias yog qhov dej tsis zoo tshaj plaws thiab yog siv dav hauv kev tiv thaiv waterproof ntawm cov ntaub ntawv tsim tsev. Txawm li cas los xij, lub methyl silicone cob cov waterproof txheej muaj siab heev thiab tsis kam tawm ntawm lub tsev, thiab dej tsis kam ua tiav tom qab ob peb hlis lossis 1 txog 2 xyoos. Nce n (ch3) / n (si) tus nqi ntawm methyl silicone resin yog conducive kom txhim kho nws hydrophobicity thiab waterproof lub neej. Guo Qingzhong thiab lwm tus pom tias Silicone Resin nrog N (CH3) / N (SI) muaj txiaj ntsig zoo tshaj plaws, thiab yuav tsum muaj cov tshuaj tiv thaiv dej tsis tu.
Peb. Nqaij iab
Siv cov qoob loo uas yog lub tsev dej tsis muaj dej muaj qhov zoo ntawm kev kho dej, cov roj, anti-oxidation, aum kev tiv thaiv, thiab saum npoo hnav tiv thaiv. Nws muaj kev nyab xeeb thiab muaj kuab paug-pub dawb thiab yog cov khoom tshiab ntawm ib puag ncig ib puag ncig. Tam sim no, xws li cov khoom tau siv dav hauv cov teb chaws txawv teb chaws rau kev tiv thaiv dej ntawm cov tuam tsev, tab sis lawv tsis tau muaj dav txhawb nqa hauv Suav teb vim yog cov kis. Hom khoom no muaj peev xwm ua lag luam zoo.
Tus neeg ua si muag siv ua tus neeg sawv cev dej Ntev ntev-saw alkyl silane yog siv los ua cov tshuaj tiv thaiv dej, thiab cov huab cua los ntawm kev ua kom muaj acidation kab lis kev cai (tshwj xeeb yog sab nraum zoov kab lis kev cai lij choj) thiab cov tsev.
Plaub. Organic silicone emulsion
Hom dej ntawm Waterproofing yog ib qho emulsion tsim los ntawm kev ua polyorganosiloxane hauv dej. Piv nrog Methyl Siliconate thiab Silicone Resinone thiab Silicone Silicone Emulsion muaj cov cwj pwm hauv qab no: nws tsis yog qhov muaj zog rau hauv cov pob zeb, pob zeb, pob zeb ua kom zoo. Tus neeg sawv cev dej no tuaj yeem raug ntxiv rau cov mis ntawm cov dej sib xyaw ua ke ua cov kab mob uas tsis muaj dej, thiab muaj peev xwm siv tau ua lub pob zeb ua si, thiab cov pob zeb ua si, xis mas, ceramics thiab Lwm cov ntaub ntawv sib xyaw ua ke, cov pob zeb ua vaj tse, cov thawv dej sab nrauv, pas dej da dej, cov dej da dej, cov dej hauv av thiab lwm yam dej num hauv av.
Muaj ntau yam hauv qab no hom emulsion-hom Silicone Waterproofing cov neeg sawv cev ncaj qha rau cov pob zeb hydrogen sib txuas, thiab yog ib pawg neeg siab xws li pawg hydroxyl los ua Network waterproof zaj duab xis; Qhov thib ob yog hydroxy silicone roj emulsion, uas tuaj yeem tau txais los ntawm ncaj emulsification lossis emulsion polymerizy ntawm roj silicone; Qhov thib peb yog alkyl alkoxy Silane emulsion, uas muaj ib pawg alkoxy thiab yog ib pawg alkoxy thiab yog qhov yooj yim los txuas cov network hydrophobic siroxane zaj duab xis.
Ntau hom ntawm cov khoom siv dej silicone waterproofing muaj kev ua yeeb yam sib txawv. Hauv kev ua haujlwm tiag tiag, ntau cov khoom lag luam feem ntau tau sib xyaw rau kev siv kom ua tiav qhov zoo tshaj plaws. Tab sis ib qho yog tus nqi hais txog: tsis muaj cov neeg tiv thaiv dej yog omnipotent thiab tuaj yeem siv ib zaug thiab rau txhua tus. Tam sim no, tus neeg sawv cev dej silicone Ntawm ib sab tes, nws yog vim nws tus nqi yog tus nqi qis thiab luv luv yog qhov zoo tagnrho; Ntawm qhov tod tes, nws yog vim hais tias lub teb chaws tseem tsis tau tsim cov khoom tshiab, thiab cia siab rau cov khoom lag luam tsis tuaj yeem sib ntsib thiab hloov kho rau kev thov kev lag luam.
Nyob rau hauv xyoo tas los, Tuam Tshoj lub tsev tsim kev lag luam dej tsis tu ncua, thiab cov kev sib tw, cov tsheb sib tw, cov kab ke, kev faib khoom, thiab cov dej phwj tuaj. Nws ntseeg tau tias tus neeg sawv cev waterproofing yuav dhau los thiab muaj ntau yam rau cov khoom siv tsis zoo thiab muaj dej siab yuav nce ib hnub. Tsuas yog cia siab rau cov neeg tuaj txawv teb tsis tuaj yeem ua tiav qhov kev thov; Ua kom muaj kev tshawb fawb thiab kev txhim kho thiab kev lag luam ntawm nruab nrab hauv nruab nrab thiab high-end tshiab waterproofing cov neeg sawv cev tau ua ib qho teeb meem maj mam ua kom daws tau.
