Yintoni umgaqo wokusebenza we-Latex Powder Proder (RDP) kubukhoboka obuxubeneyo?

I-RedEx Powx Powder (RDP) ngumgubo obalulekileyo owomileyo osetyenziselwa ukuphucula ukusebenza kodaka oluxubileyo. Umgaqo wayo wokuSebenza ikakhulu kukuphucula iimpawu eziphambili zodaka olunjengokunamathela, ukuguquguquka, ukunyangwa kwamanzi ngeendlela ezifana nokusasazeka, ukwenziwa kweefilimu kunye nokunxibelelanisa ifilimu kunye nokudibanisa kwefilimu kunye nokunxibelelanisa kwamanzi.

1. Isigaba sokusasaza
I-RDP ihlala ikho ngohlobo lomgubo oqinileyo wodaka oluxubeneyo, kwaye umphezulu wamasuntswana udibene nongqimba lwe-colloid, njenge-polyvinyl utywala (PVA), ukugcina i-polyvinyl yotywala. Emva kongeza amanzi, i-collove ekhuselweyo kwi-Latex Powder ngokukhawuleza, amasubhululu aprider aqala ukulungisa, ukukhupha ii-aruls ezincinci zokuphawula iimolekyuli zemolermer ezikhutshelwe emanzini. Le nkqubo yokusasazeka iyafana neka-emulsions, kodwa isimilo sayo kukuba ngokusebenzisa i-hydration, i-RDP inokukhawuleza ibuyele kwimeko ye-eulsions. Ngokusasazeka, i-RDP inokusasazwa ngokulinganayo kulo lonke udaka, ngaloo ndlela kuphuculwe ukunamathela kunye nokulwa nokuchasa phakathi kwemilo.

I-2. Inkqubo yokwenza ifilimu
Ngexesha lenkqubo eqinisekileyo yesamente okanye ezinye izinto ezingaqhelekanga, amasuntswana e-emulsion asasazeka yi-RDP uya kuphulukana namanzi. Xa amanzi evalisa ngokupheleleyo, amasuntswana ePolymer asasazeke yi-RDP ehlanganisana ukuze enze ifilimu yePolymer eqhubekayo. Le filimu ye-polymer idlala indima "yokudibanisa" kubume bobudaka, i-Agegregates Comgregates, ipoller emihle kwaye iphucule imihlaba kunye, iphucule kakhulu amandla odaka. Lo mhlaba wefilimu yepolymer unomfanekiso opheleleyo kunye nobunzima, kwaye unokuziqhelanisa nokungakhathali okuncinci kwezinto ezisisiseko, ngaloo ndlela ukuphuculwa kodaka. Ukongeza, ifilimu ye-polymeremer inokuthi ithintele i-micro-pores kwi-micrordor, inciphise amanzi ukuba angangeni kwi-pores, kwaye aphucule ngokufanelekileyo ukunyangwa kwamanzi kunye nokungafezeki kodaka.

I-3. Ulwakhiwo lwe-molecular kunye nokuqiniswa
I-Polymer ephambili ye-PROP idla ngokusekwe kwi-monomenem efana ne-Ethylene, i-Ethylene Acetate (Eva) okanye i-Acrylate, kwaye inobutshaba okugqwesileyo kunye nokunamathela okugqwesileyo kunye nokunamathela. Xa i-copollymers eyenziwa ngala manyanya yomile kwaye isasazeke, zinokwenza amasuntswana ahlala emanzini kwaye ekugqibeleni bakha ifilimu eqhubekayo yefilimu. Olu lwakhiwo lunobongozo obomeleleyo kunye nobunzima, kwaye bunokudlala indima yokuqinisa kubukhoboka obuxubeneyo, ukuphucula ukunganyangeki kwawo, ukuxhathisa kwempembelelo kunye nokuqina. Ngokuhlengahlengiswa komyinge we-monomer, ukusebenza kwe-patex powder kunokuguqulwa kwicala lokuhlangabezana nezidingo zodaka ezahlukeneyo.

I-4. Iziphumo eziphuculweyo
I-RDP ibonisa indlela ebalulekileyo yodaka oluxubileyo, eboniswa ikakhulu kwezi zinto zilandelayo:

Ukuphuculwa kwe-boled: Emva kwe-RDP ifihlakele, ifilimu yepolmeremer inokuvelisa i-adsorption kunye nekhemikhali enomphezulu we-subsest of the, ephucula kakhulu i-bonds kunye nodaka. Ingakumbi xa isetyenziswa njenge-amenthement kunye ne-tile ye-tile, isiphumo sokuphucula amandla aphezulu kuyacaca kakhulu.

Ukuguquguquka okuphuculweyo kunye nokungaxhathisi: Ifilimu ye-polymer emva kokuqulunqwa kwefilimu ye-RDP iyaguquguquka kwaye inokufunyanwa ngoxinzelelo olungelwe lubangelwa kukuntywila, kwaye iphucule ukunganyangeki kodaka.

Ukuphuculwa kwamanzi: Ifilimu yasePolymer eyenziwe nge-RDP inemigangatho ethile yokungena kwamanzi, enokunciphisa i-capilla yokufakelwa kwamanzi e-Cocary kwindawo yokungena kwindawo yokufuma, ngaloo ngaloo ngaloo ngaloo ndlela bephulukana nodaka lwamanzi. Ke ngoko, i-RD isetyenziswa ngokubanzi kwizifakelo ezineemfuno eziphezulu zokuthintela amanzi, ezinje ngodaka lwangaphandle lwangaphandle, udaka lwangaphandle eluntwini kunye nodaka lwamanzi.

Ukuphucula ukunxiba kunye nokuqina: Ifilimu ye-polymer inesidima esihle, esinokuphucula umonakalo wokunganyangeki kunye neemeko zempembelelo kwaye zandise ubomi benkonzo. Udaka lwe-RDP lubonisa ukungavisisani okuqinileyo phantsi kweemeko zexesha elide kwangaphandle, ukunciphisa umonakalo wokusingqongileyo kodaka.

5. Ukuphuculwa kwentsebenzo ebanzi kunye nesicelo
Ukusetyenziswa kwe-RDP kudaka kulususile kakhulu imeko yokusetyenziswa kodaka. Ngenxa yemiphumo yayo ebaluleke kakhulu ekuphuculeni amandla akwandisiweyo, ukuphucula ukungcungcutheka, ukuphucula ukunganyangeki kwamanzi okuxubeneyo njengeendawo ezahlukeneyo ezixubileyo ezifanayo, iiplati, i-DRANS, isiza sommandla wokulungisa izilwanyana. Ingakumbi kwiinkqubo zangaphandle zangaphandle, zangaphakathi kunye neeprojekthi zokulungisa ngaphandle, i-RDP iye yenye yezona zixhobo zibalulekileyo.

I-6. Iindlela zophuhliso lwexesha elizayo
Ngokuphuhliswa kwemveliso yokwakha, imfuno yezinto eziluhlaza, ezinobuhlobo kunye nezamandla ziyanda, kwaye amathuba okusebenza e-RDP kwi-rdp kwi-fes exutyweyo ibanzi kakhulu. Okwangoku, okusingqongileyo, i-VOC ephantsi (i-VOC ephantsi Ngokukodwa phantsi kwendlela yophuhliso oluzinzileyo kunye nolondolozo lwezixhobo, okuthe kuthatha indawo yezixhobo eziluhlaza zekhemikhali ezinee-bi bio eziluhlaza, ngokuthe ngcembe ukuba yindawo eshushu kwintengiso. Ukongeza, ukuphuculwa kweemveliso ze-RDP ngokuxhathisa imozulu ephezulu kunye nokunamathelisa oqinileyo ukuhlangabezana neemfuno zobunjineli phantsi kweemeko zemozulu ezigqithisileyo kuye kwaba lujoliso lophando lwexesha elizayo.

I-RDP ifumana ububi obungcono, ukuguquguquka, ukunganyangeki kwamanzi kunye nezinye iipropathi ngokusasaza, ukwenza ifilimu kunye nokomeleza ubume kwiNkqubo yokuGcoba.
