Njengesithako esibalulekileyo sepolymer,umgubo wepolymer ophinda unyibilike (RDP)Isetyenziswa kakhulu kwi-dry mortar ekhethekileyo (ezifana nezincamathelisi zethayile, ii-plaster mortars, izixhobo zokulungisa umgangatho, njl.njl.), isetyenziselwa kakhulu ukuphucula ukusebenza kwe-dry mortar. Yi-powder emhlophe, edla ngokwenziwa ngokutshiza i-polymer emulsion. Ukongezwa kwayo kwi-dry mortar akunakuphucula kuphela amandla okubopha kwe-dry mortar, kodwa kukwaphucula nokusebenza kwayo kokwakha kunye nokuqina, okubaluleke kakhulu kwezobugcisa kunye nexabiso lokusetyenziswa.
1. Iimpawu zomgubo welatex ophinda unyibilike
Umgubo welatex ophinda uqhekeke ngokuyintloko ngamasuntswana epolymer anyibilika kakuhle ngamanzi. Xa amanzi efakwa, anokuphinda aqhekeke ukuze enze i-emulsion efanayo, ngaloo ndlela enika umdaka iipropati zomzimba ezingcono. Iipolymer ezahlukeneyo (ezifana ne-acrylic acid, i-vinyl acetate, i-chloroprene, njl.njl.) zinokuvelisa iintlobo ezahlukeneyo zeepowder zelatex eziphinda ziqhekeke ezineempawu ezahlukeneyo zokusebenza. Iingenelo zayo eziphambili ziquka:
Ukunamathela okuphuculweyo: Umgubo welatex ophinda udibane unokuphucula ukunamathelana phakathi kodaka olomileyo kunye ne-substrate (ezifana neethayile, amatye, ikhonkrithi, njl.njl.), kwaye uphucule umgangatho wokwakhiwa kodaka.
Ukuguquguquka okuphuculweyo: I-mortar enomgubo we-latex ophinda unyibilike iyakwazi ukumelana nokuguquguquka okuncinci, kwaye iphephe ukuqhekeka.
Ukumelana namanzi okwandisiweyo kunye nokumelana nemozulu: Olu hlobo lwepolymer lunokuphucula ukuzinza kwesamente kwindawo enamanzi, luphucule ukumelana kwayo nokungangeni kwamanzi kunye nokumelana nemozulu, kwaye lufanelekile ngakumbi ekusetyenzisweni kwiindonga zangaphandle kunye neendawo ezinomswakama ophezulu.
Ukuphucula ukugeleza nokusebenza: Umgubo welatex ophinda udibane unokulungisa ukugeleza nokusebenza kolwakhiwo lwesamente, okwenza kube lula ukwakha nokuphepha ukuvuza kwamanzi amaninzi.
2. Indima yomgubo welatex ophinda uchitheke kwisamente esikhethekileyo esomileyo
I-mortar ekhethekileyo eyomileyo idla ngokuba luhlobo lwe-mortar eyenzelwe ukuhlangabezana neemfuno zokwakha ezizodwa, kuquka kodwa kungaphelelanga apho i-mortar yokulungisa umgangatho, i-tile adhesive, i-mortar yangaphandle yokukhusela udonga, i-dry powder coating, njl. Zihlala zifuna iipropati zomzimba nezekhemikhali ezingcono kune-mortar eqhelekileyo. Indima ye-latex powder ephinda inyibilike kwezi mveliso ibonakala kakhulu kwezi zinto zilandelayo:
2.1 Ukuqinisa ukubopha
Kwizinto zokuncamathelisa iithayile, ukubopha phakathi kweethayile kunye nezinto ezisetyenziswa phantsi kwazo kubaluleke kakhulu. Ingakumbi kwiindawo ezifumileyo, ezibandayo okanye ezishushu kakhulu, ukuzinza kokubopha kunxulumene ngokuthe ngqo nokuqina kwezinto. Ukongeza umgubo welatex ophinda uchitheke kwi-mortar kunokuphucula kakhulu ukusebenza kokubopha kwe-mortar, ngakumbi kwiindawo ezifana neethayile, amatye okanye imabula, ukuze kuthintelwe ukuxobuka komaleko wokubopha okubangelwa kukwanda kobushushu kunye nokuxinana okanye ukufuma.
2.2 Phucula ukumelana nokuqhekeka
Ukongezwa kwe-redispersible latex powder kunokuphucula ukuguquguquka kwe-mortar kwaye kuthintele ukuqhekeka kwi-mortar xa yomile, utshintsho lobushushu okanye iphantsi koxinzelelo lomzimba. Kwizicelo ezinje nge-outer wall repair mortar kunye ne-elastic plaster mortar, ukusetyenziswa kwe-redispersible latex powder kunokuphucula ngempumelelo ukumelana nokuqhekeka.
2.3 Phucula ukumelana namanzi
Umgubo welatex ophinda unyibilike kwimortar eyomileyo unokuphucula kakhulu ukumelana kwawo namanzi kunye neempawu zawo zokulwa nokungena kwamanzi. Kwiindawo ezifumileyo ezifana nezindlu zangasese kunye neekhitshi, izincamathelisi zethayile kunye nezinye izithinteli ezingangeni manzi zifuna umqobo onamandla wokufuma. Emva kokongeza umgubo welatex ophinda unyibilike, umortar unokumelana ngcono nokungena komswakama kwaye wandise ubomi bawo benkonzo.
2.4 Ukuphucula ukusebenza kakuhle kwesamente
Ukusebenza kakuhle kwe-mortar kuchaphazela ngokuthe ngqo ukusebenza kakuhle kolwakhiwo kunye nomgangatho wabasebenzi bokwakha. Ukongezwa kwe-latex powder ephinda inyibilike kunokuphucula kakhulu ukusebenza kwe-mortar, ingakumbi xa igqunywa, ngokuguquguquka okungcono kunye nokulungiswa, okwenza ulwakhiwo lube lula kwaye kunciphise ukuvuza kwamanzi.
2.5 Phucula ukumelana nokuqandusela komkhenkce
Kwezinye izicelo ezikhethekileyo, ezifana nodaka olukhusela udonga lwangaphandle kunye nodaka olulungisa umhlaba lwangaphandle, ukumelana nokunyibilika komkhenkce kubalulekile. Emva kokongeza umgubo welatex ophinda unyibilike, ukumelana nokunyibilika komkhenkce komkhenkce kuyaphucuka, okunokumelana nokuqhekeka kunye nomonakalo kwiindawo ezinobushushu obuphantsi kwaye kuhambelane neemfuno zokwakha kwiindawo ezibandayo.
3. Imizekelo eqhelekileyo yesicelo
3.1 Ithayile yokuncamathelisa
Kwi-adhesive yethayile, ukusetyenziswa kwe-redispersible latex powder kunokuphucula kakhulu amandla okubopha kwe-mortar, ngakumbi ukunamathela okuqinileyo kwiithayile zodonga kunye neethayile zomgangatho. Xa kubekwa iithayile emhlabeni okanye eludongeni, i-adhesive idla ngokufuneka ukuba ibe ne-bonding eqinileyo, ixesha elide livuleke kwaye ikwazi ukumelana namanzi amaninzi. Ukongezwa kwe-redispersible latex powder kwenza i-adhesive yethayile ifikelele ngokukhawuleza kumandla okubopha aneleyo, ngelixa iphucula uzinzo lwayo kunye nokuqina kwayo.
3.2 Idaka lokugquma udonga lwangaphandle
I-mortar yokukhusela udonga lwangaphandle isetyenziselwa unyango lokukhusela udonga lwangaphandle lwezakhiwo kwaye kufuneka ibe ne-anti-froze-thin, i-water resistance kunye ne-crack resistance. Ukongezwa kwe-latex powder ephinda inyibilike kwandisa ukuguquguquka kunye ne-water resistance ye-mortar, ngaloo ndlela kuthintela iingxaki ezinje ngokuqhekeka nokuqhekeka komaleko wokukhusela udonga, kwaye kwandise ubomi benkonzo yodonga lwangaphandle lwesakhiwo.
3.3 Ukulungiswa komgangatho wesamente
Udaka lokulungisa umgangatho lusetyenziswa kwiindlela ezahlukeneyo zokulungisa nokulungisa umgangatho, ingakumbi ukuhlaziywa kwemigangatho emidala. Ngokufaka umgubo welatex ophinda uchitheke, ukunamathela, ukunyibilika kunye nokuguquguquka kodaka kuyaphuculwa, ukuqinisekisa ukuba izinto zokulungisa umgangatho zinokwakhiwa kakuhle nangokufanelekileyo kwaye zigcine uzinzo lwexesha elide.
Njengesongezelelo esibalulekileyo kwidaka elomileyo ekhethekileyo,umgubo welatex ophinda unyibilikeidlala indima ebalulekileyo ekuphuculeni ukusebenza kwe-mortar, iphucula ukunamathela kwayo, ukumelana namanzi kunye nokumelana nokuqhekeka. Phakathi kweentlobo ezahlukeneyo zeemveliso ze-mortar ezizodwa ezomileyo, indima kunye neenzuzo zayo ziya zisanda, ngakumbi kwiindawo zokusetyenziswa kwe-tile adhesives, ii-mortars zokukhusela udonga lwangaphandle kunye nee-mortars zokulungisa umgangatho. Njengoko ishishini lokwakha liqhubeka nokwandisa iimfuno zalo zokusebenza kwezinto, ukusetyenziswa kwe-latex powder ephinda inyibilike kuya kuba kuninzi.
