I-HPMC, okanye iHydroxypropyl Methylcellulose, sithako esibalulekileyo kwimixube eyenziwe eludongeni.Kwingcaciso ebanzi, kubalulekile ukugubungela imiba eyahlukeneyo, kubandakanya ukwakheka kweekhemikhali, indima kwi-putty eludongeni, izibonelelo, usetyenziso, kunye nokuqwalaselwa kokusetyenziswa.
1.Ukwakheka kweeKhemikhali kunye neePropati:
IHydroxypropyl Methylcellulose (HPMC) yeyosapho lwe-cellulose ethers.Ubume bayo bubandakanya i-cellulose backbone chain kunye ne-hydroxypropyl kunye namaqela e-methyl aqhotyoshelweyo.Olu lwakhiwo lweekhemikhali lunika iipropati ezahlukeneyo kwi-HPMC, kuquka:
Ukugcinwa kwamanzi: I-HPMC inamandla okugcina amanzi, okuyimfuneko ukugcina ukuhambelana okufanelekileyo kwimixube ye-putty eludongeni.
Ukutyeba: Isebenza njenge-agent yokuqina, igalelo kwi-viscosity efunwayo ye-putty.
Ukusebenza: I-HPMC iphucula ukusebenza ngokuphucula ukusasazeka kunye nokunciphisa ukuthoba ngexesha lokufaka isicelo.
Ukubophelela: Inceda ekubopheni amanye amacandelo e-putty kunye, okukhokelela ekuphuculeni ukunamathela kwi-substrates.
2.Kuludwe lwe-putty eludongeni, i-HPMC isebenza ngeenjongo ezininzi:
Ulawulo oluhambelanayo: Inceda ukugcina ukuhambelana okufunwayo kwe-putty kuyo yonke inkqubo yayo, iqinisekisa ukugubungela okugudileyo kunye okufanayo.
Ukugcinwa kwamanzi: Ngokugcina amanzi ngaphakathi komxube, i-HPMC ithintela ukomisa kwangaphambi kwexesha, ukuvumela ixesha elaneleyo lokufaka isicelo kunye nokunyanga.
Uphuculo lokuncamathela: I-HPMC iphucula ukuncamathelwa kwe-putty eludongeni kwii-substrates ezahlukeneyo ezifana nekhonkrithi, i-plaster, kunye ne-masonry surfaces.
I-Crack Resistance: Iipropati zayo ezibophelelayo zinegalelo kumandla onke e-putty, ukunciphisa ukubakho kweentanda xa zomiswe.
3.Iinzuzo zeHPMC kwiWall Putty:
Ukuphuculwa kokuSebenza: I-HPMC iqinisekisa ukusetyenziswa okulula kunye nokusabalalisa i-putty eludongeni, nakwiindawo ezithe nkqo, ukunciphisa iinzame zabasebenzi.
Ukomelezwa kokuqina: Ukusetyenziswa kwe-HPMC kuphucula ukuqina kunye nokuphila ixesha elide kwi-putty layer ngokunciphisa i-shrinkage kunye nokuqhekeka.
Ukumelana naManzi: I-HPMC inceda ekuxhathiseni ukungena kwamanzi, ngaloo ndlela ikhusela i-substrate engaphantsi kumonakalo onxulumene nokufuma.
Ukuhambelana: Iyahambelana noluhlu olubanzi lwezongezelelo kunye ne-pigment esetyenziswa ngokuqhelekileyo kwimiqulu ye-putty eludongeni, evumela ukuguquguquka kwimveliso yoyilo.
Ukusebenza okuhambelanayo: I-HPMC inika iimpawu zokusebenza ezingaguqukiyo kwi-putty eludongeni kuzo zonke iimeko zokusingqongileyo kunye neemeko zesicelo.
I-4.Wall putty formulations equlethe i-HPMC ifumana usetyenziso olubanzi ku:
IiNdawo zodonga zangaphakathi kunye nezangaphandle: Zisetyenziselwa ukulungelelanisa kunye nokulinganisa iindawo zodonga ngaphambi kokupeyinta okanye i-wallpaper, ukubonelela ngesiseko esifanayo.
Ukulungisa kunye noLondolozo: I-Wall putty ene-HPMC isetyenziselwe ukulungisa iziphene ezincinci kunye neentanda, ukubuyisela ubuhle beendonga.
Ukugqitywa kokuhlobisa: Basebenza njengesiseko sokugqitywa kokuhlobisa, okwenza ukusetyenziswa kweendlela ezahlukeneyo kunye neengubo zokuphucula ubuhle.
5.Ngelixa i-HPMC ibonelela ngeenzuzo ezininzi, ukusetyenziswa kwayo okusebenzayo kufuna ingqalelo kwizinto ezithile:
Idosi efanelekileyo: Idosi efanelekileyo ye-HPMC kufuneka imiselwe ngokusekelwe kwiimfuno ezithile zokwakhiwa kwe-putty eludongeni, ngokuqwalasela izinto ezifana nokuhambelana okufunwayo kunye neemeko zesicelo.
Uvavanyo lokuhambelana: Ukuhambelana nezinye izithako kunye nezongezo kufuneka kuqinisekiswe ngovavanyo lwebhubhoratri ukuqinisekisa ukusebenza okufunwayo kunye nokuzinza kwemveliso yokugqibela.
UQinisekiso loMgangatho: Kubalulekile ukufumana i-HPMC ekumgangatho ophezulu kubaboneleli abathembekileyo ukuqinisekisa ukungaguquguquki kunye nokuthembeka kwimiqulu ye-putty eludongeni.
Ukugcinwa kunye nokuphatha: Iimeko ezifanelekileyo zokugcina, kubandakanywa ukukhuselwa kubumanzi kunye nokuvezwa kwamaqondo obushushu agqithisileyo, zibalulekile ekugcineni ingqibelelo ye-HPMC kunye nokwandisa ubomi bayo beshelufu.
IHydroxypropyl Methylcellulose (HPMC) idlala indima ebalulekileyo kwimixube eyenziwe eludongeni, ibonelela ngoluhlu lweenzuzo ezifana nokuphuculwa kokusebenza, ukuqina, kunye nokuncamathela.Ukusetyenziswa kwayo okunengqiqo, kunye nokuqwalaselwa ngokucophelela kweemfuno zokuqulunqwa kunye neemeko zesicelo, igalelo ekuphuhlisweni kweemveliso ze-putty eludongeni ezisebenza kakhulu ezifanelekileyo kwizicelo ezahlukeneyo zokwakha kunye nokugcinwa.
