Iikhompawundi zokuzilinganisa (i-SLC) zizinto ezomileyo ezikhawulezayo kunye neziguquguqukayo zomgangatho eziye zithandwa kakhulu ngenxa yokuqina kwazo okukhethekileyo kunye nomphezulu ogudileyo.Zisetyenziswa ngokubanzi kwizicelo zokuhlala kunye nezorhwebo ukulinganisa umgangatho wekhonkrithi ngaphambi kokubeka ikhaphethi, ivinyl, iplanga okanye imigangatho yeethayile.Nangona kunjalo, ukusebenza kwee-SLC kunokuchatshazelwa zizinto ezahlukeneyo zokusingqongileyo ezinje ngeqondo lobushushu, ukufuma, kunye nokubambelela kwi-substrate.Ukuphucula ukusebenza kwee-self-leveling compounds, abavelisi baye baqala ukongeza i-hydroxypropylmethylcellulose (HPMC) kunye ne-hydroxyethylmethylcellulose (HEMC) njenge-thickeners.
I-HPMC yipolymer enyibilikayo emanzini eyenza ijeli ezinzileyo xa ihlakazwe emanzini.Isetyenziswa ngokuqhelekileyo kwizicelo zezakhiwo ngenxa yokugcinwa kwamanzi okugqwesileyo kunye neempawu zokubambelela.Xa kudityaniswe iikhompawundi self-leveling, HPMC iphucula ukuhamba kunye nokusebenza umxube.Kwakhona kunciphisa umthamo wamanzi afunekayo ukufezekisa ukuhambelana okufunwayo, ukuthintela ukuncipha kunye nokuqhekeka ngexesha lokunyanga.Ukongeza, i-HPMC inokunyusa amandla adibeneyo e-SLC, ngaloo ndlela iphucula ukuxhathisa kwayo.
I-HEMC yenye i-polymer e-soluble yamanzi esetyenziswa ngokubanzi kwishishini lokwakha njenge-thickener kunye ne-rheology control agent.Inokuphucula ukubambelela, ukudibanisa kunye nokuhambelana kwezinto zokwakha, okwenza kube yinto eyongezelelweyo ethandwayo kwi-SLC.Xa ifakwe kwi-SLC, i-HEMC yandisa i-viscosity yomxube, ivumela ukuba isasazeke ngakumbi kwaye ibambelele ngakumbi kwi-substrate.Ikwaphucula iipropathi zokuzilinganisa zekhompawundi, ukunciphisa ukubakho kweziphene zomhlaba ezifana neepinhole kunye namaqamza omoya.Ukongeza, i-HEMC yonyusa amandla omatshini onke e-SLC, iyenza ibe yinto ehlala ixesha elide kwaye ingachaphazeli umonakalo.
Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kunye ne-HEMC kwi-self-leveling compounds kukuba ziphucula ukusebenza komxube.Oku kuthetha ukuba iikontraka zinokugalela kwaye zisasaze i-SLC ngokulula ngakumbi, ukunciphisa inani labasebenzi elifunekayo emsebenzini.Kwakhona, ukongeza i-HPMC kunye ne-HEMC kwi-SLC kunceda ukunciphisa ixesha lokumisa lomxube.Oku kungenxa yokuba zithintela amanzi akumxube ekubeni abe ngumphunga, nto leyo ekhokelela kwinkqubo yokuphilisa elinganayo nengaguquguqukiyo.
Enye inzuzo yokusebenzisa i-HPMC kunye ne-HEMC kwi-self-leveling compounds kukuba baphucula umgangatho opheleleyo womgangatho ogqityiweyo.Xa zongezwa kumxube, ezi polymers zonyusa ukunamathela kwe-SLC kwi-substrate, ukunciphisa ithuba lokungaphumeleli kwebhondi.Oku kuqinisekisa ukuba umgangatho uya kuhlala ixesha elide kwaye uhlale ulungile nakwi-traffic traffic.Ukongeza, ukusetyenziswa kwe-HPMC kunye ne-HEMC kudala indawo egudileyo, elungeleleneyo eyenza kube lula ukubeka ezinye izinto zomgangatho ngaphezulu.
Ngokweendleko, ukongeza i-HPMC kunye ne-HEMC kwiikhompawundi zokuzilinganisa akubizi kakhulu.Ezi polymers zifumaneka ngokulula kwimarike kwaye zinokufakwa ngokulula kwimixube ye-SLC ngexesha lemveliso.Ngokuqhelekileyo, kuphela ixabiso elincinci le-HPMC kunye ne-HEMC elifunekayo ukufezekisa ukuhambelana nokusebenza okufunekayo kwi-SLC, enceda ukugcina iindleko zokuvelisa ziphantsi.
Ekugqibeleni, ukusetyenziswa kwe-HPMC kunye ne-HEMC kwi-self-leveling compounds sisisombululo esinobuhlobo bendalo.Ezi polima ziyakwazi ukubola kwaye aziqulathanga naziphi na izinto eziyingozi, okuthetha ukuba azibeki mngcipheko kwimpilo yabantu okanye kokusingqongileyo.Ukusetyenziswa kwabo kwi-SLC kunceda ukukhuthaza ukuzinza kushishino lokwakha, ingqalelo ebalulekileyo kwihlabathi lanamhlanje.
Ukongeza i-HPMC kunye ne-HEMC kwi-self-leveling compounds ineenzuzo ezininzi, iyenza ibe sisisombululo esifanelekileyo kwiikontraka kunye nabavelisi.Ezi polymers ziphucula ukuqhutyelwa komxube, ukunciphisa ixesha lokumisa, ukuphucula umgangatho womgangatho ogqityiweyo, gcina iindleko zokuvelisa eziphantsi kunye nokukhuthaza ukuzinza.Njengoko ishishini lokwakha liqhubeka lifuna izisombululo ezintsha zokuphucula ukusebenza kakuhle, umgangatho kunye nokuzinza kweemveliso zalo, sinokubona ukusetyenziswa ngokubanzi kwe-HPMC kunye ne-HEMC kwi-SLC kwixesha elizayo.
