Umgaqo wokuSebenza we-hydroxypropyl methylcelcelcelose edaka

Hydroxypropyl methylcelculose (hpmc)Ngaba i-polymer ye-polymer ye-polymer esetyenziswe ngokubanzi kwishishini lokwakha, ngakumbi kudaka olusekwe kwisamente, udaka olusekwe kwi-gyppum kunye ne-tile. Njengoosongeziweyo, i-HPMC inokuphucula ukusebenza, ukuphucula ukusebenza, ukunamathela, ukugcinwa kwamanzi kunye nokugcinwa kwamanzi kunye nokunganyangeki kodaka, ngaloo ndlela kuphucula umgangatho wodaka.

1. Iipropathi ezisisiseko ze-HPMC

I-HPMC ifunyanwa ikakhulu kukutshintsha kwe-eterider ye-seluplose, kwaye inee-solinoity ezilungileyo zamanzi, ukwenziwa kwefilimu, i-filimu, i-thaibrity kunye nokuzinza. Iipropathi zayo ezibalulekileyo zibandakanya:

I-Solibuz yamanzi: Inokuchithwa kumanzi abandayo okanye ashushu ukwenza isisombululo se-viscous esibonakalayo okanye sokudumisa.
Isiphumo sokuqaqamba: Kunganyusa kakhulu i-viscomosity yesisombululo kwaye ibonise isiphumo esihle sokuqaqamba ngendlela ephantsi.
Ukugcinwa kwamanzi: i-HPMC inokufumana amanzi kwaye idumbe, kwaye idlale indima ekugcinweni kwamanzi kudaka ukuthintela amanzi ukuba alahleke ngokukhawuleza.
Ipropathi ye-Rheological: Ine-TIiXOTROPOP elungileyo, enceda ekuphuculeni ukusebenza kodaka.

2. Indima eyonakamileyo ye-HPMC e-shir

Indima ye-HPMC emdaka ibonakaliswa kakhulu kule miba ilandelayo:

2.1 Ukuphucula ukugcinwa kwamanzi kodaka

Ngexesha lenkqubo yokwakha yesamente, ukuba amanzi akhutshiwe ngokukhawuleza okanye athatyathwe kakhulu sisiseko, iya kukhokelela kwiNdawo yokuHlawula engaphumelelanga kwaye ichaphazele ukukhula kwamandla. I-HPMC iyenza i-mesh ye-mesh kwi-shirrdophility kunye nokwakhiwa kwamanzi kunye nokwandiswa komswakama, oko kunciphisa ixesha elivulekileyo, ngaloo ndlela kudlulisa ukulungelelaniswa kwamanzi kunye nokuphucula ukuziqhelanisa nolwakhiwo.

2.2 Ukutyibilika kweqhinga, ukuphucula ukusebenza kodaka

I-HPMC inefuthe elihle elihle, elinokunyusa i-viscofity yodaka, yenza ukuba udaka luneplastiki engcono, kwaye lukhusele udaka kwi-spotch, ukwahlula kunye nokwahlula amanzi. Kwangelo xesha, ukuqina okufanelekileyo kunokuphucula ukwakhiwa kodaka, kwenza kube lula ukufaka kunye nenqanaba ngexesha lenkqubo yokwakha, kunye nokuphucula ukusebenza kakuhle.

2.3 Ukuphucula i-Bonding kunye nokuphucula ububi bodaka

Kwizicelo ezinjenge-tile ye-tile, i-mandry farr kunye nodaka lweplastiki, amandla abunjiweyo abalulekile. I-HPMC iyenza ifilimu ye-polymer phakathi kwesiseko kunye nokudityaniswa kwesenzo sokwenza ifilimu, ephucula amandla odaka kodaka, ngaloo ndlela kunciphisa umngcipheko wokuqhekeka.

2.4 Ukuphucula ukusebenza kokuqala kunye nokunciphisa i-SAG

Ngolwakhiwo oluthe nkqo (njengokwahlulahlula i-Wall okanye indawo yokwakhiwa kwe-tile), udaka luthambekele kwi-SAG okanye ityibilika ngenxa yobunzima bayo. I-HPMC inyusa uxinzelelo lwemvume kunye ne-anti-sag yodaka, ukuze udaka lunokulungelelanisa ngakumbi kumphezulu wesiseko ngexesha lolwakhiwo oluthe nkqo, ngokwenza oko kuphuculwe uzinzo lolwakhiwo.

2.5 Ukomeleza ukunganyangeki kokuqhekeza kunye nokuphucula ukuqina

Udaka luthambile ukuba lube kukuqhekeka ngenxa yokuncipha ngexesha lenkqubo yokukhula, echaphazela umgangatho weprojekthi. I-HPMC inokutshintsha uxinzelelo lwangaphakathi lodaka kwaye inciphise ireyithi ye-shrinkage. Kwangelo xesha, ngokuphucula ukuguquguquka kodaka, kungcono ukumelana nokutshintsha kobushushu okanye uxinzelelo lwangaphandle, ngokuphucula ukuqina.

2.6 Kuchaphazela ixesha lokuseta

I-HPMC ichaphazela ixesha lokuhlala lodaka ngokuhlengahlengisa isantya sesamente yesamente. Isixa esifanelekileyo se-HPMC sinokwandisa ixesha lokwakha lodaka kwaye kuqinisekiswe ixesha elaneleyo lokuhlengahlengiswa ngexesha lokwakha, kodwa ukusetyenziswa kakhulu kunokwandisa inkqubela phambili yeprojekthi, ke idosi kufuneka ilawulwe ngokufanelekileyo.

I-3. Isiphumo se-HPMC Dosage kwi-Port Morey

Umthamo we-HPMC e-HPMC osezantsi iphantsi, ihlala iphakathi kwe-0.1% ne-0,5%. Umthamo othile uxhomekeke kuhlobo lweemfuno zodaka nokwakha:

I-Dosage esezantsi (≤0.1%): Inokuphucula ukugcinwa kwamanzi kwaye iphucule kancinci ukumiswa kodaka, kodwa isiphumo sokuqaqamba sibuthathaka.

I-Dosage ephakathi (i-0.1% ~ 0.3%): Iyaphucuka kakhulu ukugcinwa kwamanzi, ukunamathela kunye nokukwazi ukuchasana nokwandisa ukusebenza kwendlela yokwakhiwa.

I-Dosage ephezulu (≥0.3%): Iya kuwunyusa kakhulu udaka lodaka, kodwa lunokuchaphazela ulwalutho, lwandise ixesha, kwaye ungathandeki ukuba nolwakhiwo.

Njengeyona nto ibalulekileyo yodaka,I-HPMCIdlala indima ephambili ekuphuculeni ukugcinwa kwamanzi, ukuphucula ukusebenza kokwakha, ukuphucula ububi kunye nokunganyangeki. Ukongezwa kwe-HPMC kunokuphucula ukwenziwa kwentsebenzo ngokubanzi kunye nokuphucula umgangatho weprojekthi. Kwangelo xesha, umthamo kufuneka ulawulwe ukuphepha iziphumo ezibi ekusekweni kwexesha kunye nolwelo lokwakha. Kwixa elizayo, ngokuphuhliswa okuqhubekayo kwemveliso yokwakha, ithemba lesicelo le-HPMC kwizixhobo ezintsha zokwakha eziGreen ziya kuba zibanzi.
