Njengezinto eziqhelekileyo zokuhlobisa izakhiwo, i-agent ye-caulking isetyenziselwa ngokubanzi ukuzalisa izikhewu kwiitile zomgangatho, iileyile zodonga, njl. Kwiminyaka yakutshanje, kunye nokuphuculwa kweemfuno zomgangatho wokwakha, ukusebenza kwe-agent ye-caulking kuye kwahlawulwa ngakumbi nangakumbi. Phakathi kwabo, ukuchasana nokugqoka, njengesalathisi esibalulekileyo sokusebenza, kunempembelelo ngqo kubomi benkonzo kunye nomphumo wokuhlobisa we-agent caulking.IHydroxypropyl methylcellulose (HPMC), njenge-polymer yendalo esetyenziswa ngokuqhelekileyo, isetyenziswa rhoqo njenge-thickener, i-arhente yokugcina amanzi, i-rheology modifier, njl. kwi-agent ye-caulking. Ukongezwa kwe-HPMC akunakuphucula kuphela ukusebenza kokwakhiwa kwe-agent ye-caulking, kodwa nokuphucula ukuxhathisa ukunxiba kwinqanaba elithile.
1. Iimpawu ezisisiseko ze-HPMC
I-HPMC yikhompawundi yepholima efunyenwe ngokuguqulwa kweekhemikhali zemicu yezityalo zendalo (ezifana nentlaka yeplanga okanye umqhaphu), enonyibiliko olugqwesileyo lwamanzi kunye nokubola okuhle kokuphila. Njenge-thickener, i-HPMC inokulungelelanisa i-rheology ye-agent ye-caulking kwaye iphucule ukusebenza kwayo ngexesha lokwakha. Ukongezelela, i-AnxinCel®HPMC inokuphucula nokugcinwa kwamanzi kwi-caulking agents, ukuphepha ukuqhekeka kunye nokuwa okubangelwa ukulahlekelwa kwamanzi kwangaphambili kwi-caulking agents. Ngoko ke, i-HPMC isetyenziswa ngokubanzi kwi-adhesives, i-coatings, i-caulking agents kunye nezinye iimveliso kushishino lokwakha.
2. Ukugqoka ukuxhathisa kwee-caulking agents
Ukumelana nokunxiba kubhekiselele kwisakhono sesixhobo sokumelana nokunxiba phantsi kwamandla angaphandle. Kwii-caulking agents, ukunyanzeliswa kokugqoka kubonakala ngokukodwa kwinto yokuba ubuso bayo awonakali lula, buhluthwe okanye bunamanqaku acacileyo okugqoka ngenxa yokuxhatshazwa kwexesha elide. Ukumelana nokunxitywa kwee-caulking agents kubalulekile kubomi benkonzo yezithuba kwimigangatho nakwiindonga, ngakumbi kwiindawo ezihlala zisesichengeni sokungqubana koomatshini okanye kuxinene ngabantu, njengodederhu lweevenkile, iindawo zikawonke-wonke, amakhitshi, amagumbi okuhlambela kunye nezinye iindawo. Ii-caulking agents ezinokumelana nokunxiba kakubi ziya kukhokelela ekulahlekeni okwandisiweyo kwezixhobo kwizithuba, ezichaphazela umphumo wokuhlobisa kwaye zingabangela iingxaki ezifana nokuphuma kwamanzi.
3. Impembelelo ye-HPMC kwi-resisance resistance of caulking agents
Ukuphucula iimpawu ze-rheological ze-caulking agents
Ukongezwa kwe-AnxinCel®HPMC kunokuphucula kakhulu iimpawu ze-rheological ze-caulking agents. Isiphumo salo sokuqina senza ukuba i-agent e-caulking ibe nezakhiwo ezingcono zokwakha, igweme i-sag phenomenon ebangelwa ukuhlanjululwa ngokugqithiseleyo kwezinto ngexesha lokusetyenziswa, kunye nokwandisa amandla okubambisana kwe-agent caulking. Ukongezelela, ukuqina okufanelekileyo kunokuqinisekisa ukuchaneka komlinganiselo we-agent caulking, ukwenzela ukuba ifake isakhiwo esifanayo ngexesha lenkqubo yokuqina kunye nokunciphisa amathuba okuba nama-pores okanye ama-cracks. Ezi zinto ngokungangqalanga ziphucula ukunyanzeliswa kokugqoka kwendawo ye-agent ye-caulking, kuba i-uniform kunye nesakhiwo esiqinileyo sinokumelana kangcono nesenzo samandla angaphandle.
Ukuphucula ukuxhathisa kwamanzi kunye nokugcinwa kwamanzi kwi-agent agent
I-solubility yamanzi kunye nokugcinwa kwamanzi kwe-HPMC nayo idlala indima ebalulekileyo ekuxhathiseni ukunxiba kwe-agent caulking. I-HPMC inokulibazisa ngokufanelekileyo ukuguquguquka kwamanzi e-ejenti ye-caulking, iqinisekise ukuba izinto zigcina amanzi aneleyo ngexesha lenkqubo yokuqina, ngaloo ndlela iphucula ukuqina kwayo kunye namandla. Amandla aphezulu anceda i-agent ye-caulking surface ixhathise ngcono ukunxiba kunye nokunciphisa iingxaki ezinjengokuqhekeka, ukukhupha isanti kunye nokuchithwa okubangelwa kukunyuka kwamanzi amaninzi.
Yenza isakhiwo sothungelwano oluzinzileyo
Indima ye-HPMC kwi-agent ye-caulking ayiphelelanga ekuxineni. Isenokwenza isakhiwo sothungelwano esizinzileyo kunye nezinye izithako ezifana nesamente kunye negypsum. Esi sakhiwo sinokunyusa ukuxinwa kwefayili, okwenza ukuba ubuso baso bube nzima kwaye bunxibe ngakumbi. Isakhiwo sothungelwano somhluzi oqinileyo sinokumelana ngokuphumelelayo nempembelelo yamandla angaphandle afana nokuxubha kunye nokungcangcazela, ukunciphisa ukunxiba komhlaba. Uzinzo lwesakhiwo sothungelwano lunxulumene ngokusondeleyo nobunzima bemolekyuli kunye neqondo lokuthatha indawo ye-HPMC. I-HPMC enobunzima obuphezulu bemolekyuli kunye neqondo eliphakathi lokuthatha indawo inokubonelela ngokumelana nokunxiba okunamandla.
Ukuphucula ukuchasana kwempembelelo yesigcwalisi
Iimpawu ezilastiki ze I-AnxinCel®HPMC yenza ukuba isigcwalisi sisasaze ngcono uxinzelelo xa sichatshazelwa ngamandla angaphandle, ukuphepha ukuqhekeka okanye amaqhekeza abangelwa uxinzelelo olugqithisileyo lwendawo. Olu xhathiso lwempembelelo luhambelana ngokusondeleyo nokuxhatshazwa kokugqoka, kuba ngexesha lenkqubo yokukhuhlana, umphezulu wokugcwalisa unokuthi ube phantsi kwamandla amancinci, ukwandisa umngcipheko wokugqoka izinto eziphathekayo. Ukongezwa kwe-HPMC kwandisa ukuqina kwesithambiso, okwenza kube lula ukuphuka phantsi kwengxabano.
4. Isicwangciso sokuphucula se-HPMC kwi-resistance resistance of filler
Ukuze kuphuculwe ngakumbi ukuxhathisa kokunxiba kwe-HPMC kwisigcwalisi, abaphandi kunye neenjineli banokwandisa kwezi nkalo zilandelayo:
Khetha iintlobo ezifanelekileyo ze-HPMC: Ubunzima bemolekyuli kunye neqondo lokuthatha indawo ye-HPMC kunempembelelo ethe ngqo ekusebenzeni kwefayili. I-HPMC enobunzima obuphezulu bemolekyuli idla ngokuba nefuthe elingcono lokutyeba kunye neempawu zerheological, kodwa ubunzima obukhulu bemolekyuli bunokukhokelela kwiipropati zokwakha ezincitshisiweyo. Ngoko ke, xa ukhetha izinto eziphathekayo, kuyimfuneko ukukhetha iindidi ezifanelekileyo ze-HPMC ngokweemfuno zemeko yesicelo esithile.
Lungisa ubungakanani be-HPMC eyongeziweyo: Ubungakanani obufanelekileyo be-HPMC bunokuphucula ukuxhatshazwa kwe-agent ye-caulking, kodwa ukudibanisa ngokugqithiseleyo kunokubangela ukuba umphezulu we-agent ye-caulking ube nzima kakhulu kwaye uswele u-elasticity owaneleyo, ngaloo ndlela kuchaphazela ukuchasana kwayo kwempembelelo. Ke ngoko, kuyafuneka ukugqiba elona nani lifanelekileyo le-HPMC elongeziweyo ngovavanyo.
Ukuhambelana nezinye izithako: Kwisiseko seHPMC, ukongeza ezinye iifayili ezifana nokuqiniswa kweefayili kunye ne-nanomaterials kunokuphucula ngakumbi ukuxhatshazwa kwe-agent ye-caulking. Ngokomzekelo, izinto ezifana ne-nano-silicon kunye ne-nano-alumina zinokwenza i-microscopic yokuqinisa isakhiwo kwi-agent ye-caulking, iphucula kakhulu ubunzima bomhlaba kunye nokuxhatshazwa kokugqoka.
Njengesongezo esibalulekileyo kwi-arhente ye-caulking, i-HPMC inokuphucula kakhulu ukuxhathisa ukunxiba ngokuphucula iimpawu ze-rheological, ukugcinwa kwamanzi, ubunzima kunye nokuchasana kwempembelelo ye-agent caulking. Ngokukhetha ngokufanelekileyo uhlobo kunye nenani le-AnxinCel®HPMC, idibene namanye amanyathelo okuphucula, ubomi benkonzo ye-agent ye-caulking inokwandiswa ngokufanelekileyo ukuze kuqinisekiswe ukusebenza kwayo kakuhle kwiindawo ezahlukeneyo ezinzima. Ngokuphuculwa okuqhubekayo kweemfuno zokusebenza kwezinto zokwakha, amathuba okusebenza kwe-HPMC kwii-caulking agents abanzi kwaye afanele uphando olongezelelweyo kunye nophuhliso.
