I-Putty powder off inkinga ye-powder

I-De-powdering and whitening of internal wall putty powder okwamanje yizinkinga ezivame kakhulu ngemva kokwakhiwa kwe-putty.Ukuze uqonde izizathu ze-putty powder de-powdering yangaphakathi, umuntu kufanele aqale aqonde izingxenye eziyisisekelo zezinto ezibonakalayo kanye nezimiso zokuphulukisa ze-putty powder yangaphakathi, bese uhlanganisa Ngesikhathi sokwakhiwa kwe-putty, ukoma kwendawo yodonga, izinga lokumuncwa kwamanzi, izinga lokushisa. , ukoma kwesimo sezulu, njll., thola izizathu eziyinhloko ze-powder drop of the putty powder odongeni lwangaphakathi futhi usebenzise indlela ehambisanayo yokuxazulula inkinga ye-powder drop of the putty powder.

Ukwakheka okuyisisekelo kwempahla eluhlaza ye-interior wall putty powder:

Izithako eziyisisekelo kakhulu ze-putty powder yangaphakathi zifaka: izinto zokubopha ezingaphili (i-ash calcium), izigcwalisi (impushana ye-calcium esindayo, i-talcum powder, njll.) izithasiselo ze-polymer (HPMC, i-polyvinyl alcohol, impushana yerabha, njll.)

Phakathi kwazo, i-putty powder yangaphakathi yodonga ngokuvamile ayifaki usimende omhlophe noma ingeza kuphela inani elincane likasimende omhlophe.Impushana ye-latex ehlakazeka kabusha inomphumela omncane esimweni somthamo ophansi, ngakho-ke ayisetshenziswa odongeni lwe-putty powder ikakhulukazi ngenxa yezindleko, noma ayivamisile ukusetshenziswa.

Ngakho-ke ngenxa yenkinga yodonga lwangaphakathi lwe-putty powder formula ngokwayo:

1. Izinto zokuhlanganisa ezingaphili, njengokwengezwa kwe-calcium yomlotha ziphansi kakhulu, futhi izinga le-ash calcium alikho ezingeni;

2. Uma inani lengxenye ye-bonding ku-additive ye-polymer liphansi kakhulu noma izinga lingekho ezingeni elijwayelekile, lingabangela ukuba i-putty powder odongeni lwangaphakathi iwe.

Ihlukaniswe yaba izici ezilandelayo:

01. Amandla okunamathela we-putty akwanele ukubangela ukususwa kwe-powder.Umkhiqizi wehlisa izindleko ngobumpumputhe.Amandla okunamathela we-rubber powder ampofu futhi inani lokwengeza lincane, ikakhulukazi i-putty yangaphakathi yodonga.Izinga le-rubber powder kanye neglue lihlobene kakhulu nenani elingeziwe.

02. Ifomula yokuklama ayinangqondo, inkinga yokukhethwa kwezinto kanye nesakhiwo kubaluleke kakhulu kufomula ye-putty.Isibonelo, i-hydroxypropyl methylcellulose (HPMC) isetshenziswa njenge-putty engangeni manzi odongeni lwangaphakathi.Nakuba i-HPMC ibiza kakhulu, ayisebenzi kuma-fillers afana ne-double fly powder, i-talcum powder, i-wollastonite powder, njll. Uma kuphela i-HPMC isetshenziswa, izobangela i-delamination.Kodwa-ke, i-CMC ne-CMS ngamanani aphansi ayisusi i-powder, kodwa i-CMC ne-CMS ayikwazi ukusetshenziswa njenge-putty engenamanzi, futhi ayikwazi ukusetshenziswa njenge-putty yangaphandle yodonga, ngoba i-CMC ne-CMS isabela nge-gray calcium powder kanye nosimende omhlophe, okuzobangela delamination.Kukhona futhi i-polyacrylamides engezwe ku-lime calcium powder kanye nosimende omhlophe njengezimbotshana ezingangeni manzi, okuzophinde kubangele ukusabela kwamakhemikhali kubangele ukukhishwa kwempushana.

03. Ukuxuba okungafani nokugqugquzela kuyisizathu esiyinhloko sokukhishwa kwe-powder kwe-putty ezindongeni zangaphakathi nangaphandle.Abanye abakhiqizi ezweni bakhiqiza i-putty powder ngemishini elula nehlukahlukene.Akuzona izinto ezikhethekile zokuxuba, futhi ukuxuba okungalingani kubangela ukukhishwa kwe-putty powder.

04. Iphutha ohlelweni lokukhiqiza libangela ukuthi i-putty ibe yimpuphu.Uma i-mixer mixer ingenawo umsebenzi wokuhlanza futhi kunezinsalela ezengeziwe, i-CMC ku-putty evamile izosabela nge-ash calcium powder ku-putty engangeni manzi.I-CMC, i-CMS kanye ne-Simende emhlophe ye-putty yangaphandle yodonga iyasabela futhi ibangele ukubola kwempuphu.Imishini ekhethekile yezinkampani ezithile ifakwe ichweba lokuhlanza, elingahlanza izinsalela emshinini, hhayi kuphela ukuqinisekisa ikhwalithi ye-putty, kodwa futhi ukusebenzisa umshini owodwa ngezinjongo eziningi, futhi uthenge umshini owodwa ukukhiqiza izinhlobonhlobo ezihlukahlukene. i-putty.

05. Ikhwalithi yama-fillers nayo kulula ukubangela i-de-powdering.Inani elikhulu lama-filler asetshenziswa ngaphakathi nangaphandle odongeni putty, kodwa okuqukethwe kwe-Ca2CO3 ku-powder ye-calcium esindayo kanye ne-talc powder ezindaweni ezihlukahlukene kuhlukile, futhi umehluko ku-pH uzophinde ubangele ukubola kwe-putty, njenge-Chongqing kanye ne-powdering. I-putty powder ye-Chengdu yangaphakathi yodonga isebenzisa impushana yerabha efanayo, kodwa impushana ye-talcum nempushana ye-calcium enzima kuhlukile.Ayisusi impushana e-Chongqing, kodwa isusa impuphu e-Chengdu.Ayisusi impuphu e-Henan naseNyakatho-mpumalanga ye-China, kodwa isusa impuphu kwezinye izindawo.

06. Isizathu sesimo sezulu siyisizathu sokukhishwa kwempuphu ye-putty ezindongeni zangaphakathi nangaphandle.Isibonelo, i-putty ezindongeni zangaphakathi nangaphandle inesimo sezulu esomile kanye nomoya omuhle kwezinye izindawo ezomile enyakatho.Ezinye izindawo zinesimo sezulu esinemvula, umswakama wesikhathi eside, izakhiwo ze-putty ezakha ifilimu azilungile, futhi zizolahlekelwa yimpushana, ngakho-ke ezinye izindawo zifaneleka i-putty engenamanzi ne-ash calcium powder.

07. Izibophezelo ze-Inorganic ezifana nempushana ye-calcium empunga nosimende omhlophe zingcolile futhi ziqukethe inani elikhulu le-Shuangfei powder.Okubizwa ngokuthi i-multi-functional grey calcium powder kanye nosimende omhlophe osebenza ngezinto eziningi emakethe angcolile, ngoba kusetshenziswa inani elikhulu lalezi zibophezelo ezingcolile ze-inorganic, futhi i-putty engangeni manzi yezindonga zangaphakathi nangaphandle nakanjani izoba ngaphandle kwempushana. futhi hhayi amanzi.

08. Ehlobo, ukugcinwa kwamanzi kwe-putty odongeni lwangaphandle akwanele, ikakhulukazi ezindaweni ezishisa kakhulu nezinomoya omncane njengeminyango namafasitela aphakeme.Isikhathi sokuqala sokubeka i-ash calcium powder kanye nosimende asanele, futhi amanzi azolahleka.Uma inganakekelwa kahle, izophinde ibe yimpushana kakhulu .
