Indlela yokuphucula ukwakhiwa kweselulosi eludongeni lobushushu obuphezulu ehlotyeni

Okwangoku, sele kuza kungena ehlotyeni, kwaye iqondo lobushushu liphezulu kakhulu, ngakumbi kummandla osemantla.Ubushushu buphezulu kwaye nomoya womile.Ubushushu bomphezulu wodonga bungafikelela kuma-60°C.Ngenxa yobushushu, i-cellulose ihlala ineengxaki ezifana nokwakhiwa kakubi kunye nokususwa komgubo ngexesha lokwakha.Isizathu esona sizathu kukuba ngenxa yokushisa okuphezulu kwodonga, ukugcinwa kwamanzi kwi-putty akulungile, ngoko ke amanzi kwi-putty axutywe ngokukhawuleza okanye aphuphume eludongeni, ukwenzela ukuba i-putty ayinakuphinda ifakwe kwaye ikhutshwe.Kuvela umngxuma kunye nokuxobula.Indlela yokuphucula ukugcinwa kwamanzi kwiputty yangaphandle eludongeni ikakhulu ineendlela ezilandelayo:

1. Yandisa isixa se-cellulose ether

I-ether ye-cellulose inokugcinwa kakuhle kwamanzi, kodwa ukusebenza kokugcinwa kwamanzi akunyuki emva kokuba inani elithile le-cellulose ether yongezwa.Ngelo xesha, ukwanda kwe-cellulose kwandisa i-viscosity ye-putty kwaye ukwakhiwa akulula.Ukongeza, ixabiso le-putty liyanda.

2. Ukwandisa inani le-lignocellulose

I-Lignocellulose inesiphumo esithile sokugcina amanzi.Ukongezwa kwefiber yomthi kuphucula amandla okugcina amanzi ezinto eziphathekayo, kwenza inkqubo yezinto eziphathekayo i-hydrated ngokulinganayo, kwaye inokuphucula ukusebenza ngexesha elifanayo, kodwa umgaqo wokugcinwa kwamanzi we-lignocellulose uhluke kwi-cellulose.Inophawu lokufunxa iinwele.(Ukuqhuba kwamanzi), kuya kubakho umswakama phakathi kwefayibha nganye, kwaye xa umswakama kwindawo ejikelezileyo yefiber utshintsha kwaye uyancipha, ukufuma phakathi kweefayili kuya kukhutshwa ngokulinganayo.Ixesha elivulekileyo, akukho lula ukukrazula.Nangona kunjalo, ngenxa yokuba ubukhulu be-putty eludongeni lwangaphandle buncinci kakhulu, ubukhulu bengubo ye-scrape nganye yi-0.5-1mm kuphela.Xa ubushushu bomgangatho womgangatho wesiseko kunye nobushushu bomoya buphezulu kakhulu, ukusebenza kwawo kokugcinwa kwamanzi akucaci, kwaye ukusebenza ngokuphindaphindiweyo kokwaleka kwe-scrape kuphakathi.

3. Ukwandisa umthamo wepolymer

Kwiindonga ezine-putty encinci, umoya owomileyo kunye nobushushu obuphezulu besiseko, ukunyusa umthamo wepolymer yenye yeendlela ezingcono zokwenza i-putty ibe neepropati eziphindaphindiweyo zokukrala, kodwa ixabiso le-latex powder ehlaziyiweyo liphezulu kakhulu, isixa esikhulu siya kunyuka kakhulu. ixabiso putty.Kwakhona kunokudlala indima engcono ngokudibanisa umgubo omncinci wepolyvinyl utywala, kodwa i-viscosity yepolyvinyl alcohol powder inkulu kakhulu, eya kuchaphazela ukusebenza, kunye nepropati yesanti ye-putty ayilungile..

4. Yongeza i-lubricant ye-polymer

Ngovavanyo, kuthathwa njengokhetho olungcono lokongeza i-lubricant ephezulu kwi-putty eludongeni lwangaphandle kwindawo yobushushu obuphezulu ehlotyeni.I-lubricant iyingxenye ye-polymer compound, kwaye i-lubricant ye-rheological ijolise ikakhulu ekuphuculeni ukusebenza kolwakhiwo kwinkqubo ye-cement-based.Ixesha elivulekileyo kunye nokusebenza okufanayo.Yandisa ukusebenza kunye nokuxhathisa i-sag ye-mortars, i-plasters, i-renders, i-plasters kunye ne-adhesives kwaye inqande ukuchithwa kwe-samente yokulinganisa.Isizathu sokugcinwa kwamanzi kukuba kukho inani elikhulu lamaqela asebenzayo e-hydrophilic kwikhonkco layo le-molecular.Kwimeko yokukrala ngokuphindaphindiweyo kunye nokugquma, ayiyi kulahlekelwa ngamanzi, inomsebenzi obalaseleyo wokugcina amanzi, kwaye i-thickening kunye ne-thixotropy ngexesha elifanayo, okwenza ulwakhiwo lube lula kwaye lungathatha indawo ye-cellulose, kodwa ixabiso layo liyi-cellulose ether kuphela, kwaye umthamo wayo 0.1-0.2%., yinto ebiza kakhulu, ukuba isetyenziswe kunye ne-cellulose ether, i-lignocellulose, kunye ne-redispersible latex powder, umphumo uya kuba ngcono.
