Isicwangciso esitsha sokuhonjiswa kodonga lwangaphandle
Izinto ezintsha zokuhombisa iindonga zangaphandle eziphuhliswe kwiminyaka yakutshanje zifaneleke kakhulu ukuhombisa udonga lwangaphandle lwee-gymnasiums, amathala eencwadi, izikolo, iivillas kunye nezinye izakhiwo.Inzuzo ephambili kukwenza umhlobiso wokwakha, kwaye inokuphinda ifezekise imiphumo yokugcinwa kobushushu kunye nokugcinwa kwamandla, ukushisa kunye nokufakwa kwesandi, ukukhupha amanzi kunye ne-mildew.Masiyibone kunye.
Iibhodi zokuxhoma iindonga zangaphandle ze-PVC zenziwe ngokukodwa ngezinto ezinzima ze-polyvinyl chloride, ezinemisebenzi yokugubungela, ukwakhiwa okulula kunye nokukhawuleza, ukukhuselwa kunye nokuhlobisa.Kwaye inokuphinda isetyenziswe kwaye iphinde isetyenziswe, into yokwakha eluhlaza ekhuthaza ukukhuselwa kwendalo.Kulula ukuyicoca ngexesha lokusetyenziswa kwaye ayifuni ukugcinwa;iyabiza, kwaye ineengenelo zokunqanda ilangatye, ukuxhathisa ukufuma, ukuxhathisa umhlwa, kunye nokumelana nokuguga.Ngokutsho kophando, ubomi benkonzo yePVC yangaphandle yodonga lokuhombisa i-siding ingafikelela kwiminyaka engaphezu kwama-30, kwaye Iyakwazi ukumelana nokuhlaselwa kwemozulu embi, okwenza isakhiwo sibonakale sisitsha iminyaka emininzi.Ngokuqhelekileyo, izakhiwo ezisezantsi zisetyenziswaIbhodi yokuxhoma yangaphandle ingasetyenziselwa kuluhlu olubanzi lokubanda kunye nokushisa, okuhlala ixesha elide kunye ne-anti-ultraviolet kunye nokuguga.Inokumelana ne-corrosion efanelekileyo kwi-asidi, i-alkali kunye netyuwa.Akukho ngcoliseko, inokuphinda isetyenziswe;ukusebenza kakuhle kokusingqongileyo.Kulula ukucoca kunye nokuphelisa emva kokugcinwa.Udonga lwangaphandle lwangaphandle lulungile ekuchaseni umlilo.Ilitye linokumelana nomlilo.Ibhodi yefiber sement yiBanga A, ilandelwa yiPVC yangaphandle yodonga.Isalathisi se-oksijeni sinqande ilangatye kunye nokuzicima emlilweni;idibana nomgangatho wokukhusela umlilo we-GB-T, kunye ne-Siding yangaphandle yodonga lwentsimbi okwangoku iBanga B. I-siding ephezulu yokugcina amandla kwiindonga zangaphandle.Icala elingaphakathi le-PVC siding kwiindonga zangaphandle linokufakwa ngokulula kunye nezinto zokufakelwa kwe-thermal ezifana ne-polyfoam, eyenza udonga lwangaphandle lwe-thermal insulation lube njengokubeka umaleko we "cotton" endlwini ngelixa i-PVC siding Yiyo "ingubo."
