I-Hydroxypropyl starch ether (HPS) sisongezo sekhemikhali esisetyenziswa ngokuqhelekileyo kwizinto zokwakha kwaye idlala indima ebalulekileyo kwiidaka. Isitashi esilungisiweyo esiphucula kakhulu ukunyibilika, i-viscosity kunye neempawu ze-rheological zesitashi ngokuzisa amaqela e-hydroxypropyl kwikhonkco le-molecular chain. Ezi zakhiwo zenza ukusetyenziswa kwe-hydroxypropyl starch ether kwi-mortar inzuzo ezininzi.
1. Ukuphucula ukugcinwa kwamanzi
Omnye weyona misebenzi ibalulekileyo ye-hydroxypropyl starch ether kukuphucula ukugcinwa kwamanzi kudaka. Ukongeza i-HPS kwidaka kunokuphucula kakhulu amandla okugcina ukufuma kodaka. Le propati ineempembelelo ezibalulekileyo kulwakhiwo kunye nokusebenza kwezinto eziphathekayo. Ukugcinwa kwamanzi okwandisiweyo kuyanceda:
Yandisa ixesha lokusebenza (ixesha lokuvula) lodaka: Ngexesha lenkqubo yokwakha, ukuphuphuma kwamanzi kodaka ngokukhawuleza kakhulu kuya kubangela ukuba udaka lulahlekelwe ngamanzi kwangoko, ngaloo ndlela lunciphisa ixesha lokusebenza kwalo. I-HPS igcina ukufuma okufanelekileyo, iqinisekisa ukuba abafake izicelo banexesha elaneleyo lokufaka isicelo kunye nokulungelelanisa.
Ukunciphisa ukuqhekeka okomileyo: Ukuba udaka lulahlekelwa ngamanzi ngokukhawuleza ngexesha lenkqubo yokuqina, ukuqhekeka okomileyo kuya kwenzeka ngokulula, okuchaphazela umgangatho wokugqibela womgangatho kunye namandla okwakhiwa. Umthamo wokugcina amanzi we-HPS unokuthintela ngokufanelekileyo oku ukuba kungenzeki.
2. Ukuphucula ukusebenza kolwakhiwo
I-Hydroxypropyl starch ether inokuphucula kakhulu ukusebenza kodaka. Oku kubandakanya imiba efana neempawu zerheological, ukuthambisa kunye nokulawulwa kwe-viscosity yodaka. Ukusebenza okuthe ngqo kuku:
Ukuphucula ulwelo kunye nokuxhathisa kwe-sag: I-HPS inokunyusa umbane wodaka, okwenza kube lula ukusasazeka ngexesha lokwakha. Kwangaxeshanye, kuba inokuphucula i-viscosity yodaka, inokuthintela udaka ukuba ungagxuphuleki kwindawo ethe nkqo kwaye ugcine ukusasazeka okuhle kunye nokuzinza komphezulu othe nkqo.
Ukuphucula i-lubricity: Ngexesha lenkqubo yokwakha, i-lubricity yodaka inceda ukunciphisa ukungqubuzana ngexesha lomsebenzi wokwakha kwaye yenza isicelo sibe lula, ngaloo ndlela kuncitshiswe ubunzima bokwakha kunye nokuphucula ukusebenza kakuhle.
Ukulawula i-viscosity: I-HPS inokulawula ngokufanelekileyo i-viscosity yodaka, ukuze ibe ne-fluidity enhle kwaye inokuqina ngokukhawuleza emva kwemisebenzi yokwakha ukwenza isakhiwo esizinzile.
3. Ukwandisa amandla okudibanisa
Ukuphucula amandla okubopha udaka ngomnye umsebenzi obalulekileyo we-HPS. Ngokuphucula iipropathi zokuhlangana phakathi kodaka kunye ne-substrate, i-HPS inako:
Amandla ebhondi aphuculweyo: Ibhondi eyongeziweyo phakathi kodaka kunye ne-substrate inokuphucula amandla kunye nokuqina kwenkqubo yonke. Ngokukodwa kwiimeko apho i-high-power bonding iyadingeka, i-HPS inokuphucula kakhulu umphumo wokudibanisa udaka.
Ukuphucula ukubambelela: Xa usebenzisa udaka, i-HPS inokunceda udaka lunamathele bhetele kumphezulu wezinto ezisisiseko, ukunciphisa i-delamination kunye nokuchithwa kodaka, kunye nokuqinisekisa umgangatho weprojekthi.
4. Phucula ukuxhathisa ukunyibilika komkhenkce
I-Hydroxypropyl starch ether nayo ineenzuzo ezibalulekileyo malunga nokumelana nemozulu yodaka. Inokuphucula ukuxhathisa ukunyibilika kodaka, ngokukodwa ngolu hlobo lulandelayo:
Ukunciphisa umonakalo ovela kwimijikelezo yokuqhaqha: Ukufuma kumdaka kuya kwanda kwaye kunqanyulwe ngokuphindaphindiweyo ngexesha lomjikelo wokuqhaqhazela, kubangela umonakalo kwisakhiwo sodaka. Ukugcinwa kwamanzi kunye nokuthambisa kwe-HPS kunokunciphisa umonakalo wamanzi kwisakhiwo sodaka ngexesha lenkqubo yokukhenkceza kunye nokuphucula ukunyanzeliswa kwe-frize-thaw yodaka.
Ukuphuculwa kokuqina: Ngokunciphisa umonakalo owenziwe ngumkhenkce, i-HPS inceda ekuphuculeni ukuqina kwexesha elide lodaka, evumela ukuba igcine ukusebenza kakuhle kwiindawo ezahlukeneyo ezinzima.
5. Ukubonelela ngokusebenza kakuhle kolwakhiwo
Ukusetyenziswa kwe-HPS kudaka kuzisa nokusebenza ngcono kolwakhiwo. Oku kubonakala ikakhulu kwi:
Kulula ukuxuba kunye nokuxuba: Ukongezwa kwe-HPS kwenza udaka lube lufana ngakumbi ngexesha lokuxuba, ukunciphisa ukuhlanganiswa kwamaqamu kunye namaqhekeza ngaphakathi kodaka, ngaloo ndlela kuphuculwe ukufana kokuxuba.
Ukunciphisa ukopha: Ukopha kumdaka kuya kubangela ukuba ifilimu yamanzi ibonakale phezu kodaka, ngaloo ndlela ichaphazela umgangatho wokwakha. I-HPS inokuthintela ngokufanelekileyo ukopha kwaye igcine ukuhambelana kunye nokuzinza kodaka.
6. Ukhuseleko lokusingqongileyo kunye nokhuseleko
Njengesongezo esisingqongileyo, i-hydroxypropyl starch ether ithandwa kakhulu kwizinto zokwakha zanamhlanje. Iipropati zayo ezikhuselekileyo nezingenabuthi zenza ukuba zisetyenziswe ngokubanzi kwizicelo zokwakha ezahlukeneyo, ngokuhambelana neemfuno eziphezulu zangoku zokukhuselwa kwendalo kunye nokhuseleko kwishishini lokwakha.
Indima ye-hydroxypropyl starch ether kwi-mortar ayiphuculi kuphela ukugcinwa kwamanzi, ukusebenza kolwakhiwo kunye namandla okubopha udaka, kodwa iphakamisa ukuxhathisa ukunyibilika kodaka, ibonelela ngokusebenza kakuhle kolwakhiwo, kwaye ihambelana nokukhuselwa kwendalo kunye nemigangatho yokhuseleko. . Ezi mpawu zenza i-HPS ibe yinto eyimfuneko kunye neyongezelelweyo ebalulekileyo kwizinto zokwakha zanamhlanje, ezibonelela ngenkxaso eqinile yokuphucula ukwakhiwa kwezakhiwo kunye nomgangatho wezinto eziphathekayo.
