I-HPMC (iHydroxypropyl Methyl Cellulose) sisixhobo sepolymer esisetyenziswa kakhulu kwizixhobo zokwakha, ingakumbi kwizixhobo ezisekwe kwisamente nakwizixhobo ezisekwe kwi-gypsum. Inokunyibilika kakuhle kwamanzi, inamathela, igcina amanzi kwaye ityeba, ngoko ke isetyenziswa kakhulu kwi-mortar, i-putty powder, i-tile adhesive kunye nezinye izinto.
1. Izizathu zokuncipha nokuqhekeka kwezinto zokwakha
Ngexesha lenkqubo yokuqina, izixhobo zokwakha zihlala zincipha ngenxa yokuphuma kwamanzi, iikhemikhali kunye notshintsho kwizinto zangaphandle ezingqongileyo, nto leyo ekhokelela ekuxinzelelekeni koxinzelelo kunye nokwakheka kweentanda. Iintlobo eziphambili zokuncipha ziquka:
Ukuncipha kweplastiki: Xa izinto ezisekwe kwisamente zingakaqini, umthamo uyancipha ngenxa yokuphuma kwamanzi ngokukhawuleza.
Ukushwabana okomileyo: Emva kokuba izinto ziqinile, zibonakaliswa emoyeni ixesha elide, aze amanzi aphele kancinci, nto leyo ebangela ukushwabana komthamo.
Ukuncipha kobushushu: Utshintsho lomthamo olubangelwa kukutshintsha kobushushu, ingakumbi kwindawo enomahluko omkhulu wobushushu phakathi kwemini nobusuku.
Ukuncipha kwe-Autogenous: Ngexesha lenkqubo yokufunxa isamente, umthamo wangaphakathi uyancipha ngenxa yokutyiwa kwamanzi yimpendulo yokufunxa.
Oku kuncipha kudla ngokukhokelela ekuqokeleleni koxinzelelo ngaphakathi kwezinto, ekugqibeleni kubangele ukuqhekeka okanye ukuqhekeka, okuchaphazela ukuqina kunye nobuhle besakhiwo sesakhiwo. Ukuze kuthintelwe le meko, izongezo zihlala zifuneka ukuphucula ukusebenza kwezinto, kwaye i-HPMC yenye yazo.
2. Indlela yokusebenza kwe-HPMC
I-HPMC idlala indima ebalulekileyo ekunciphiseni ukushwabana nokuqhekeka kwezinto zokwakha, nto leyo ephunyezwa ikakhulu ngeendlela ezilandelayo:
Ukugcinwa kwamanzi: I-HPMC inomthamo oqinileyo wokugcina amanzi kwaye inokwenza ifilimu yokugcina amanzi kwi-mortar okanye kwi-putty powder ukuze inciphise izinga lokuphuma kwamanzi. Ekubeni ukuphuma kwamanzi ngokukhawuleza ngaphakathi kwezinto kuya kubangela ukuncitshiswa kweplastiki, isiphumo sokugcina amanzi se-HPMC sinokunciphisa ngempumelelo ukuncipha kokuqala, sigcine amanzi kwizinto ezaneleyo, ngaloo ndlela sikhuthaze ukusabela okupheleleyo kokufuma kwesamente kwaye sinciphise ukuqhekeka okubangelwa kukulahleka kwamanzi ngexesha lenkqubo yokomisa. Ukongeza, i-HPMC inokuphucula ukusebenza kwezinto phantsi kweemeko ezimanzi nezomileyo kwaye inciphise ukuqhekeka okubangelwa kukulahleka kwamanzi.
Isiphumo sokuqina nokuqinisa: I-HPMC sisithambisi esinokunyusa ngokufanelekileyo ukuhambelana kunye nokuxinana kwesamente kwaye siphucule ukunamathelana kwayo yonke into. Ngexesha lenkqubo yokwakha, ukuba izinto zincinci kakhulu, kulula ukuzihlukanisa okanye ukuzibhidliza, nto leyo ebangela ukuba umphezulu ungalingani okanye ukuqhekeka. Ngokusebenzisa i-HPMC, isamente sinokugcina ukuxinana okufanelekileyo, siphucule amandla kunye noxinano lomphezulu wento emva kokwakhiwa, kwaye sinciphise amathuba okuqhekeka. Ukongeza, i-HPMC inokuphucula ukumelana nokunqunyulwa kwezinto kwaye iphucule ukumelana kwazo nokuqhekeka.
Ukuphucula ukuguquguquka kwezinto: Iimolekyuli ze-HPMC zinokudlala indima ethile ekuphuculeni ukuguquguquka kwezinto ezisekwe kwisamente okanye kwizinto ezisekwe kwi-gypsum, ukuze izinto zibe nokumelana nokugoba okungcono emva kokunyangwa. Ekubeni izinto zokwakha zihlala ziphantsi koxinzelelo lokugoba okanye lokugoba phantsi kotshintsho lobushushu kunye nemithwalo, emva kokongeza i-HPMC, ukuguquguquka kwezinto kuyanda, okunokuthatha ngcono uxinzelelo lwangaphandle kwaye kuthintele ukuqhekeka okubuthathaka.
Lawula izinga lokuphendula ngokufunxa isamente: Kwizinto ezisekwe kwisamente, isantya sokuphendula ngokufunxa siyayichaphazela ngqo indlela esebenza ngayo into. Ukuba impendulo yokufunxa isamente ikhawuleza kakhulu, uxinzelelo olungaphakathi kwento alunakukhululwa ngexesha, nto leyo ebangela ukuqhekeka. I-HPMC inokulibazisa ngokufanelekileyo izinga lokuphendula ngokufunxa amanzi ngokugcinwa kwayo kwamanzi kunye nokwakheka kwefilimu ekhuselayo, ithintele isamente ekulahlekelweni ngamanzi ngokukhawuleza kwinqanaba lokuqala, kwaye ngaloo ndlela iphephe into yokushwabana okuzenzekelayo kunye nokuqhekeka ngexesha lenkqubo yokuqina kwezinto.
Ukuphucula ukusebenza kolwakhiwo: I-HPMC inokuphucula ukusebenza kolwakhiwo lwezixhobo zokwakha, ikakhulu ngokuphuma kwayo kakuhle, ukugcinwa kwamanzi kunye nokuthamba, yonyusa ukufana kwezinto, kwaye inciphise imingxunya ebangelwa kukwakhiwa okungafanelekanga. Ingenza kube lula ukusasaza i-mortar, i-putty powder, njl.njl. ngexesha lokwakhiwa, inciphise umlinganiselo we-void wezixhobo, iphucule uxinano kunye namandla ezixhobo, kwaye inciphise umngcipheko wokuqhekeka kwendawo okubangelwa kukwakhiwa okungalinganiyo.
3. Ukusetyenziswa kwe-HPMC kwizixhobo zokwakha ezithile
I-adhesive yethayile: I-HPMC inokuphucula kakhulu ukusebenza kwe-adhesive yethayile engatyibilikiyo, iqinisekise ukuba iithayile zinokuncamathiselwa ngokulinganayo kwi-substrate ngexesha lokufakwa, kwaye inciphise ukuqhekeka okanye ukuqhekeka okubangelwa kuxinzelelo olungalinganiyo okanye ukushwabana. Ukongeza, iziphumo zokutyeba kunye nokugcinwa kwamanzi ze-HPMC zikwavumela i-adhesive yethayile ukuba igcine ixesha elide ivulekile emva kokwakhiwa, iphucule ukusebenza kakuhle kokwakhiwa, kwaye inciphise ukuqhekeka okubangelwa kukungatshibiliki okungalinganiyo.
Umgubo wePutty: Kwi-putty powder, ipropathi yokugcina amanzi ye-HPMC inokuthintela i-putty ekulahlekelweni ngamanzi ngokukhawuleza ngexesha lenkqubo yokomisa, kwaye inciphise ukushwabana kunye nokuqhekeka okubangelwa kukulahleka kwamanzi. Kwangaxeshanye, isiphumo sokuqina se-HPMC sinokuphucula ukusebenza kolwakhiwo lwe-putty, okwenza kube lula ukuyisebenzisa ngokulinganayo eludongeni, kwaye kuncitshiswe ukuqhekeka komphezulu okubangelwa kukusetyenziswa okungalinganiyo.
I-mortar: Ukongeza i-HPMC kwi-mortar kunokuphucula ukusebenza kwayo ngempumelelo, kwenze i-mortar ibe lula ngexesha lokwakha, kunciphise ukwahlulwahlulwa kunye nokuhluzwa, kwaye ngaloo ndlela kuphucule ukufana kunye nokunamathela kwe-mortar. Kwangaxeshanye, isiphumo sokugcina amanzi se-HPMC sinokwenza amanzi aphele kancinci ngexesha lenkqubo yokuqina kwe-mortar, kuthintelwe ukushwabana nokuqhekeka okubangelwa kukulahleka kwamanzi kwangoko.
4. Amanyathelo okhuseleko okusebenzisa i-HPMC
Ulawulo lomlinganiselo: Ubungakanani be-HPMC eyongeziweyo bunempembelelo ngqo kwisiphumo sayo, kwaye ngokuqhelekileyo kufuneka ilungiswe ngokwemilinganiselo yezinto kunye neemeko ezithile zokusetyenziswa. I-HPMC egqithisileyo iya kubangela ukuba izinto zibe nokuhambelana okuphezulu kakhulu, okuchaphazela ukusebenza kolwakhiwo; ngelixa i-HPMC enganeleyo ayiyi kukwazi ukudlala indima yokugcina amanzi kunye nokuqina njengoko kufanele.
Sebenzisa nezinye izongezo: I-HPMC idla ngokusetyenziswa kunye nezinye izongezo zamakhemikhali (ezifana nezinciphisi zamanzi, ii-air entraining agents, ii-plasticizers, njl.njl.) ukuze kufumaneke iziphumo ezingcono. Xa usebenzisa, kuyimfuneko ukuqwalasela ukusebenzisana kwezongezo ezahlukeneyo ukuze kuthintelwe impembelelo efanayo ekusebenzeni kwezinto.
Njengesongezelelo esibalulekileyo sesakhiwo, i-HPMC inefuthe elikhulu ekunciphiseni ukuqhekeka nokuqhekeka kwezixhobo zokwakha. Inciphisa ngempumelelo ukuqhekeka okubangelwa kukulahlekelwa ngamanzi kunye noxinzelelo ngokuphucula ukugcinwa kwamanzi, ukuqina, ukuguquguquka kwezinto kunye nokuphucula izinga lokusabela kwamanzi kwisamente. Ukusetyenziswa ngokufanelekileyo kwe-HPMC akunakuphucula kuphela ukusebenza kolwakhiwo lwezinto, kodwa kwandise nobomi benkonzo yesakhiwo kwaye kunciphise iindleko zokugcinwa kamva. Ngokuqhubeka nokuqhubela phambili kwetekhnoloji yezinto zokwakha, ukusetyenziswa kwe-HPMC kwicandelo lokwakha kuya kuba kubanzi kwaye kunzulu.
