Indima ye-HydroxyPOpyl Methylcelceltulose (i-HPMC) kwizifakelo kwaye inikezela
Ukuzala kwaye kubhalwa kudlala indima ebalulekileyo ekwakheni, ukubonelela ngengqibelelo yendlela, ukumelana nemozulu, kunye nokuba nesibongozo. Kwiminyaka edlulileyo, ukuqhubela phambili kwezixhobo zokwakha kukhokelele kuphuhliso lwezinto ezongezwayo ukonyusa iipropathi zokufaza kunye nokunikezela. Enye into eyongeziweyo yokufumana udumo yi-hydroxypropyl methylcelsele (i-HPMC).
Ukuqonda i-HPMC:
Hydroxypropyl methylcelculose (hpmc)Ngaba i-nonic se-ionsulose i-ether ivela kwi-polymers yendalo, ngokuyintloko i-Selelose. Idityaniswe ngokusabela kwi-alkali selsulose ne-methyl chloride kwaye i-proplenene oxide. I-HPMC isetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanya nolwakhiwo, amayeza, ukutya, kunye ne-cosmetics, ngenxa yezinto eziguquguqukayo.
Iipropathi ze-HPMC:
Ukugcinwa kwamanzi: i-HPMC icofa ifilimu ecekeceke xa idityaniswa namanzi, ukuphucula amandla okugcina amanzi kunye nokunikezela. Oku kuthintela ukomisa ngaphambi kwexesha, ukuqinisekisa ukuhamba-hydications okhethekileyo kwizinto zesamente kunye nokuphucula ukusebenza.
Ukuphuculwa kokuphuculwa: Ukongezwa kwe-HPMC kunika isiphumo se-idabring, kuqhubele ukusasazeka kunye nokusetyenziswa kwezifaki kunye nokusebenza. Iphucula ukuhlangana kunye nokungqinelana komxube, kukhokelela ekugqibiseni.
Umlinganiso: I-HPMC ixhasa utyekelo lwezifaki-zifa kunye kwaye zinikezela kwiintengo ezinamanye, ezinjengekhonkrithi, izitena, kunye nelitye. Oku kukhuthaza iibhondi ezomeleleyo, ukunciphisa umngcipheko wokulibazisa okanye ukuhlutha ngokuhamba kwexesha.
Inyuke ixesha elivulekileyo: Ixesha elivulekileyo libhekisa kwixesha apho udaka okanye umbhalo ohlala uhlala ungasebenzi ngaphambi kokuseta. I-HPMC idlulisela ixesha elivulekileyo ngokulibazisa ukufaka umxube, ukuvumela ukusetyenziswa okungcono kunye nokugqibezela, ngakumbi kwiiprojekthi ezinkulu.
Crack Resistance: The addition of HPMC improves the flexibility and elasticity of mortars and renders, reducing the likelihood of cracking due to shrinkage or thermal expansion. Oku kuphucula ukuqina kunye nobomi bobuqili.
Izibonelelo ze-HPMC kwi-SRRs kwaye zilungelelaniswe:
Ukungaguquguquki:I-HPMCUkuqinisekisa ukufana kodaka nokunikezelwa kwemixube, ukunciphisa ukwahluka kwezinto ezifana namandla, ukungcungcutheka, kunye nokunamathela. Oku kukhokelela ekusebenzeni okungaguqukiyo kunye nomgangatho kwiibatch ezahlukeneyo.
Ukusetyenziswa kwezinto: I-HPMC inokubandakanywa ku-Rirr oNzulu kunye nokuSebenza, kubandakanya isamente esekwe, kusekwe kwi-limes, kunye neenkqubo ezisekwe gypsim. Icaciswa kakuhle kwiimeko ezahlukeneyo kunye neemeko zokusingqongileyo, zenza ilungele uluhlu olubanzi lwezicelo.
Ukuqina: isifa ngesandla kwaye sibomelezwe nge-HPMC Visives Ukungaxhathisi izinto ezikhoyo kwindalo esingqongileyo njengokufuma, ukuguquguquka kobushushu, kunye nokuvezwa kweefilimu. Oku kuphucula ukuqina ngokubanzi kunye nokuqina kwesakhiwo.
Ukuhambelana: I-HPMC iyahambelana nezinye izinto ezongezelelwayo kunye nokungqinelana okuqhelekileyo kusetyenziswa kudaka kunye nokunikezelwa, ezinje ngeearhente zokungena komoya, izixhobo zeplasitiki, kunye ne-pozbholoc. Ayiphazamisi ukwenziwa kwezi zinto zongezelelo, ivumela imiphumo yobunye.
Ukusetyenziswa kwe-HPMC kwi-HPMC kunye nokuGcina:
I-Renderst engaphandle: I-HPMC Aba bantu banikezela ngokugqwesileyo, ukuguquguquka, kunye nokunganyangeki, ukuphucula imbonakalo kunye nokuqina kwezakhiwo.
Ababukeli be-tiles: I-HPMC yinto ebalulekileyo yeTile Dhessheves, ukuphucula amandla e-boing amandla kunye nokuphucula udaka olunamathela. Iqinisekisa ukumanzi okufanelekileyo kunye nokugubungela umhlaba kwaye uthintele umntu owome ngaphambi kwexesha.
Ukulungisa izifakazi: Ukulungiswa kwe-HPMC-fitsions isetyenziselwa ukuphathwa, ukuphinda kuvunwe, kunye nokubuyisela izakhi zekhonkrithi ezonakalisiweyo. Aba bantu bathanda ukubethelela ngokugqwesileyo kunye nokuhambelana nekhonkrithi esele ikho, kuqinisekisa ukulungiswa okungagungqiyo.
I-Skim Coats: I-Skim Cooke, isetyenziselwa ukwenziwa kwenqanaba kunye nokuncwina kwendawo engalinganiyo, ukuxhamla ngokongezwa kwe-HPMC. Inika ukungangqinelani okukuko kwingubo ye-skim, ivumela ukusetyenziswa ngokulula kwaye kufezekisile ukugqiba okugudileyo, iyunifomu.
Hydroxypropyl methylcelculose (hpmc)Idlala indima ebalulekileyo ekwandiseni intsebenzo, ukusebenza, kunye nokuqina kwamakhonkco kwaye kunikezelwa kwizicelo zokwakha. Ipropathi yayo eyahlukileyo, njengokugcinwa kwamanzi, ukuphuculwa kokusebenza, ukunamathela, kunye nokunyangwa, kwenza ukuba i-adsorting yexabiso eliphezulu kunye nezakhi eziphelileyo. Njengoko ishishini lokwakha liyaqhubeka ukuba livele, ukusetyenziswa kwe-HPMC kulindeleke ukuba kunyuswe, ukuqhuba ubuchule kunye nokuzinza kwezinto zokwakha.
