Njengesembatho esijwayelekile sokwakha umhlobiso, i-ejenti ye-caulking isetshenziswa kabanzi ukugcwalisa izikhala kumathayili phansi, amathayili odonga, njll. Ukuqinisekisa ukuthopha, ubuhle nokubekwa uphawu kobuso. Eminyakeni yamuva nje, ngokuthuthuka kwezidingo zekhwalithi yokwakha, ukusebenza kwe-ejenti ye-caulking sekukhokhelwe ngokwengeziwe. Phakathi kwazo, gqoka ukumelana, njengenkomba yokusebenza ebalulekile, unomthelela oqondile empilweni yenkonzo kanye nomphumela wokuhlobisa we-caulking agent.I-Hydroxypropyl methylcellulose (HPMC), njenge-polymer yemvelo evame ukusetshenziswa, imvamisa isetshenziswa njengomuntu omkhulu, i-ejenti yokugcina amanzi, i-rheology modifier, njll. E-Caulking Agent. Ukungezwa kwe-HPMC akunakuthuthukisa ukusebenza kwe-ejenti ye-caulking, kepha futhi kuthuthukisa ukumelana kwayo kokugqoka ngezinga elithile.
1. Izici eziyisisekelo ze-HPMC
I-HPMC iyindawo eyi-polymer etholwe ukuguqulwa kwamakhemikhali kwemicu yezitshalo zemvelo (njenge-solip yokhuni noma ukotini), enokotini okuhle kakhulu kwamanzi kanye ne-biodegradadamatability enhle. Njengomkhulu, i-HPMC ingaguqula i-Rheology ye-ejenti ye-caulking futhi ithuthukise ukusebenziseka kwayo ngesikhathi sokwakha. Ngaphezu kwalokho, i-Coxincchel®hpmpc nayo ingathuthukisa ukugcinwa kwamanzi kwama-caulking agents, ukugwema ukuqhekeka nokuwa okubangelwa ukulahleka kwamanzi ngaphambi kwesikhathi kwama-caulking agents. Ngakho-ke, i-HPMC isetshenziswa kabanzi ekunamathisineni, ukumboza, ama-ejenti e-caulking kanye neminye imikhiqizo embonini yezokwakha.
2. Gqoka ukumelana kwama-caulking agents
Ukuvinjelwa kokuvinjelwa kusho amandla okuqukethwe ukuze umelane nokugqoka ngaphansi kwamandla angaphandle. Ku-caulking agents, ukumelana kokugqoka kuboniswa ikakhulukazi eqinisweni lokuthi ingaphezulu layo alilimele kalula, lihlelwe noma linophawu olusobala noma lugqoke amamaki wesikhathi eside ngenxa yokuxabana kwesikhathi eside ngenxa yokungqubuzana kwesikhathi eside ngenxa yokungqubuzana kwesikhathi eside ngenxa yokungqubuzana kwesikhathi eside. Ukumelana nokugqokwa kwama-caulking agents kubalulekile empilweni yenkonzo yezikhala eziphansi nasezindongeni, ikakhulukazi ezindaweni ezivame ukuvezwa ku-mechan racing noma izitolo ezinkulu, izindawo, amakhishi, amakamelo okugeza kanye nezinye izindawo. Ama-ejenti e-caulking anokuvikelwa kabi kokuvikeleka azoholela ekulahlekelweni kwezinto ezisetshenziselwa izikhala, okuthinta umphumela wokuhlobisa futhi kungadala izinkinga ezinjengekhasi le-water.
I-3. Umphumela we-HPMC ekumelaneni nokugqokwa kwama-caulking agents
Ukwenza ngcono izakhiwo ze-Rheological of Caulking Agents
Ukungezwa kweCicken®hpmc kungathuthukisa kakhulu izakhiwo ze-rheological zama-caulking agents. Umphumela wayo wokuqina wenza umenzeli we-caulking abe nezakhiwo ezingcono zokwakha, uvimbela into ye-sag ebangelwa ukujaha ngokweqile kwezinto ezibonakalayo ngesikhathi sokusebenzisa, futhi ithuthukise amandla okubopha we-caulking agent. Ngaphezu kwalokho, ukuqina okufanele kungaqinisekisa ukunemba kwesilinganiso kwe-ejenti ye-caulking, ukuze kwakha isakhiwo esifanayo ngesikhathi senqubo enzima futhi kunciphise amathuba ama-pores noma imifantu. Lezi zinto zithuthukisa ngokungaqondile ukumelana nokugqokwa kwe-caulking carce, ngoba iyunifomu kanye nesakhiwo esiqinile singamelana kangcono nesenzo samabutho angaphandle.
Thuthukisa ukumelana kwamanzi nokugcinwa kwamanzi kwe-ejenti ye-caulking
I-solubility yamanzi nokugcinwa kwamanzi kwe-HPMC nakho kudlala indima ebalulekile ekumelaneni nokugqokwa kwe-caulking. I-HPMC ingabambezela ngempumelelo ukuthambekela kwamanzi amenzeli we-caulking, qiniseka ukuthi lokho okuqukethwe kugcina amanzi anele ngesikhathi senqubo enzima, ngaleyo ndlela kuthuthukise ukuqina namandla ayo okuqina. Amandla aphezulu asiza ubuso be-caulking ejenti ukumelana nokugqoka okungcono futhi banciphise izinkinga ezinjengokuqhekeka, i-sanding kanye nokuchitheka okubangelwa ukuhwamuka kwamanzi ngokweqile.
Yakha isakhiwo senethiwekhi esizinzile
Iqhaza le-HPMC ku-ejenti le-caulking alilinganiselwe ekukhulekeni. Kungabuye kwakha isakhiwo senethiwekhi esizinzile nezinye izithako ezifana nesimende ne-gypsum. Lesi sakhiwo singakhulisa ubuntu bakwaFiller, okwenza ukuthi kube nzima kakhulu nokugqokwa. Ukwakheka kwenethiwekhi ye-filler elukhuni kungamelana ngempumelelo nomthelela wamabutho angaphandle anjengengxabano nokudlidliza, ukunciphisa ukugqokwa komhlaba. Ukuqina kwesakhiwo senethiwekhi kuhlobene kakhulu nesisindo samangqamuzana kanye nezinga lokufaka esikhundleni se-HPMC. I-HPMC enesisindo esiphakeme samangqamuzana kanye nesilinganiso esilinganiselwe sokufakwa esikhundleni sokufaka esikhundleni sokuvikelwa okuqinile.
Ngcono ukumelana nomthelela we-filler
Izici ze-Eastic ze ICECCINCELX®HPMC inika amandla i-filler ukusakaza kangcono ukucindezela lapho kuthinteka amabutho angaphandle, ukugwema imifantu noma izingcezwana ezibangelwa ukucindezelwa kwendawo ngokweqile. Lokhu kumelana nomthelela kuhlobene kakhulu nokugqoka ukumelana, ngoba ngesikhathi senqubo yokungqubuzana, ingaphezulu le-filler lingabekwa ngaphansi kwamandla amancane amathonya, andise ubungozi bokugqoka okubonakalayo. Ukungezwa kwe-HPMC kuthuthukisa ubunzima beflicker, kwenze kube mancane amathuba okuthi aphule ngaphansi kwezingxabano.

Ukuze uphinde uthuthukise ukumelana nokugqokwa kwe-HPMC ku-filler, abacwaningi nonjiniyela bangakhulisa kulezi zinto ezilandelayo:
Khetha izinhlobo ezifanele ze-HPMC: isisindo samangqamuzana kanye nezinga lokufaka esikhundleni se-HPMC linomthelela oqondile ekusebenzeni kwe-filler. I-HPMC enesisindo esiphakeme samangqamuzana imvamisa inomphumela wokuqina okungcono kanye nezakhiwo ze-rheological, kepha ziphezulu kakhulu isisindo samangqamuzana zingaholela ekunciphiseni izakhiwo zokwakha. Ngakho-ke, lapho ukhetha izinto zokwakha, kuyadingeka ukuthi ukhethe izinhlobo ezifanele ze-HPMC ngokuya ngezidingo zesimo esithile sohlelo lokusebenza.
Lungisa inani le-HPMC elingeziwe: Inani elifanele le-HPMC lingathuthukisa ukumelana kwe-ejenti ye-caulking, kepha ukungezwa ngokweqile kungadala ukuthi ingaphezulu le-caulking e-caulking libe nzima futhi linokuqina olwanele kakhulu, ngaleyo ndlela lithinta ukumelana nathi kwalo. Ngakho-ke, kuyadingeka ukuthola inani elifanele le-HPMC elingezwe ngokusebenzisa izivivinyo.
Ukuhambisana nezinye izithako: ngesisekelo seI-HPMC, engeza amanye ama-filler afana nemicu yokuqinisa kanye nama-nanomatadium angathuthuka ngokuqhubekayo ukumelana nokugqokwa kwe-caulking. Isibonelo, izinto ezifana ne-nano-silicon ne-nano-alumina zingakha isakhiwo esiqinisa ama-microscopic ku-ejenti ye-caulking, ngcono kakhulu ukumelana kwayo komhlaba kanye nokugqoka.
Njengesengezo esibalulekile ku-ejenti ye-caulking, i-HPMC ingathuthukisa kakhulu ukumelana kwayo kokugqoka ngokwenza ngcono izakhiwo ze-rheological, ukugcinwa kwamanzi, ubulukhuni kanye nokumelana nomthelela we-caulking agent. Ngokukhetha ngokoqobo uhlobo nenani le-ComfinCel®HPMC, elihlanganiswe nezinye izindlela zokusebenzisa imali, impilo yensizakalo ye-caulking ejenti inganwetshwa ngempumelelo ukuze kuqinisekiswe ukusebenza kwayo okuhle ezindaweni ezahlukahlukene eziyinkimbinkimbi. Ngokuthuthuka okuqhubekayo kwezidingo zokusebenza kwezinto zokwakha, amathemba wesicelo se-HPMC kuma-caulking agents abanzi futhi afanele ukucwaninga okwengeziwe kanye nentuthuko.
