Kucacile kwabo bakwishishini ukuba i-pvc yangaphandle yokuxhoma ibhodi yodonga luhlobo olutsha lokuhombisa kunye nezinto zokuhombisa.Le mveliso yenziwe ngoluhlu lweenkqubo ezifana nokuxuba kunye nokufudumeza kwe-pvc resin kunye nezongezo zangaphandle.Le mveliso inesakhiwo esihle kunye nexabiso eliphantsi.Kufanelekile ukuhlobisa iindonga zangaphakathi nangaphandle, iishedi kunye ne-eaves.Makhe sijonge oku kulandelayo kunye nomhleli omncinci ovela kumnatha wokuhombisa.
Iimpawu ze-pvc zodonga lwangaphandle
1. Ukuhlobisa okulungileyo
Imbonakalo yodonga lwangaphandle lwe-pvc luthatha ukulinganisa ukuthungwa komthi, kwaye umphezulu wokulinganisa iinkozo zomthi kunye nezinye iipateni zahlukile.Inobuhle obulula kunye nendalo obuthathu.Inemibala eyahlukeneyo kunye nokuyila ukuthungwa.Ifektri, izakhiwo zorhwebo, iindawo zokuhlala ezinemigangatho emininzi kunye nokulungiswa kwezakhiwo zakudala, njl.
Okwesibini, ukusetyenziswa kwezinga elikhulu
Ibhodi yokuxhoma i-pvc yangaphandle yodonga yimpahla ekhethekileyo edibeneyo ehlanganiswe ngokufanelekileyo kunye ne-anti-ultraviolet anti-disorder agent yexesha elide, echasene nokubanda kunye nokushisa, okuqinileyo, i-ultraviolet kunye ne-anti-aging.Ilungile kakhulu ekuxhathiseni ukubola kwi-alkali, ityuwa kunye neendawo ezifumileyo, inokumelana nemozulu eyahlukeneyo enzima, inokuhlala njengentsha phantsi kweempembelelo zemozulu ezahlukeneyo zendalo, kulula ukuyicoca (inokuhlanjwa), kwaye ayinakukhusela (akukho ipeyinti kunye nokwaleka okufunekayo).).
3. Ukusebenza kakuhle komlilo
Isalathiso se-oksijini ye-pvc yangaphandle eludongeni siding yi-40, i-flame retardant kunye nokuzicima kude nomlilo, ihambelana nomgangatho wokukhusela umlilo we-B-level (gb-t 8627⑼9).
4. Ukonga amandla aphezulu
Umaleko wangaphakathi we-pvc wangaphandle webhodi yokuxhoma eludongeni unokuba lula kakhulu ukufaka izinto ze-polyethylene foam, ukwenzela ukuba umphumo wodonga lwangaphandle ube ngcono.
Izinto ze-polyethylene ze-foam zifana nokubeka i-"coat coat" endlwini, kunye nebhodi yokuxhoma eludongeni lwangaphandle "ingubo", indlu ifudumele ebusika kwaye ipholile ehlobo, kwaye ukugcinwa kwamandla kuhle kakhulu.
5. Ufakelo olulula
Ibhodi yokuxhoma i-pvc yangaphandle yodonga inesakhiwo esiphezulu, kulula ukuyifaka kwaye iqinile kwaye inokwethenjelwa.I-villa ye-200 square metres inokufakwa ngosuku olunye.Iprojekthi yodonga lwangaphandle lwecala yeyona nto igcina umsebenzi kunye nesisombululo sokuhlobisa ngaphandle kodonga lwangaphandle.Ukuba kukho umonakalo oyingxenye, kufuneka utshintshe kuphela ibhodi entsha yokuxhoma, elula kwaye ekhawulezayo, kwaye ukhuseleko lufanelekile.
6. Ubomi benkonzo ende
1. Ngokuqhelekileyo, ubomi benkonzo yemveliso ubuncinane iminyaka emibini okanye emihlanu, kwaye ubomi benkonzo ye-double-layer co-extrusion imveliso kunye nomphezulu wemveliso asa ye-American ge (General Electric) inkampani ingaphezulu kwe Iminyaka engama-30.
Isixhenxe, ukhuseleko olulungileyo lokusingqongileyo
Udonga lwangaphandle lwe-pvc alungcolisi imo engqongileyo kwinkqubo yokuvelisa okanye kwindlela yobunjineli, kwaye inokuphinda isetyenziswe.Yinto efanelekileyo yokuhlobisa ukhuseleko lokusingqongileyo.
8. Inzuzo enkulu ebanzi
Inkqubo yokufakela ibhodi yokuxhoma i-pvc yangaphandle eludongeni ilula kwaye ikhawuleza, wonke umsebenzi owomileyo, uqinile kwaye unokwethenjelwa, onokunciphisa kakhulu ixesha lokwakha.
Itekhnoloji yokwakhiwa kwebhodi yokuxhoma eludongeni lwangaphandle lwe-pvc
1. Okokuqala, linganisa ukuqina kwekona yangaphandle yomgangatho kunye nokuthe tye kwesiqalo esithe tye.Ukuba impazamo inkulu kakhulu, kufuneka uthetha-thethane neQela A ngemilinganiselo yolungiso, kwaye ulwakhiwo lunokwenziwa kuphela emva kokuba iQela A livumile;
2. Ngokwenkqubo yokufakela ibhodi yokuxhoma, faka kuqala izixhobo (iposti yekona yangaphandle, indawo yekona yangaphakathi, umgca wokuqala, umgca we-J), uze ufake ibhodi yokuxhoma.Kufuneka kubekho ubuncinane ezintandathu ukwandiswa phakathi kwebhodi yokuxhoma kunye nekona yomgca (ulwalathiso oluthe tye).indawo
3. Ngenxa yokuba udonga lunoluhlu lwe-thermal insulation, iibholiti zokwandisa iplastiki kunye nezikrufu zisetyenziselwa ukulungisa ibhodi yokuxhoma.Ubude obupheleleyo beebholithi zokwandiswa kukuba: ubukhulu bomgangatho wokufakelwa kwe-thermal + ubukhulu bodaka lwesamente + 35, udonga olunzulu alukho ngaphantsi kwama-30, kunye nobubanzi be-screw yensimbi yeSine, ububanzi bentloko. ingabi ngaphantsi kwesibhozo.Lungisa ibholithi e-1 yokwandisa rhoqo ngo-601750px, kwaye ulungise isikrufu sentsimbi esi-1 rhoqo nge-30-1000px.Udonga lwangaphandle lwecala ngokwalo lolohlobo lwezinto ezilula zokuhombisa umzimba.Ubunzima bemitha nganye yesikwere se-siding malunga neekhilogram ezi-2.Ubuncinci iibholiti zokwandisa ezintandathu kunye nezikrufu ezisibhozo kufuneka ziqhutywe kwimitha enye yesikwere.Ngokomyinge, ibholiti nganye yokwandisa (isikrufu) Umthamo wokuthwala umthwalo umalunga neekhilogram eziyi-0.16.Ngaphambili, siye saqhuba iimvavanyo zesampulu kwizitena zokufakelwa kwe-thermal kwiindonga zeeprojekthi ezifanayo.Iibholiti zokwandiswa kunye nezikrufu zinamandla kwaye ziqinile ngokwaneleyo ukujamelana nobunzima obuvela kwibhodi yokuxhoma ngokwayo kunye neqondo elithile lamandla angaphandle (njengomoya);
4. Isikhonkwane sentsimbi kufuneka sibethelelwe embindini womngxuma wezikhonkwane.Akuvumelekanga ukubethelela kwibhodi yebhodi ngaphandle komngxuma wesikhonkwane ukukhusela umgangatho webhodi ukuba uphume kwaye uphazamiseke ngenxa yokwandiswa kunye nesithuba sokunciphisa.Kufuneka kubekho umsantsa phakathi kwentloko yezikhonkwane kunye nebhodi yokuxhoma.Izikhonkwane ziqine kakhulu;
Xa iibhodi ezimbini zokuxhoma zifakwe kunye, isixa esithe kratya yi-25⑸0, kunye neflange yebhodi enye ejingayo kufuneka inqunyulwe ukwenza umjikelo ube mcaba ngakumbi.Ndiyakholelwa ukuba wonke umntu uya kuba nokuqonda okungaphezulu okanye okungaphantsi komxholo ongasentla, ndiyathemba ukuba eli nqaku linokukunceda.Unako nokungena ku-www.marlenecn.com ukujonga kwaye ubhalisele umxholo onxulumene ngakumbi kunye nolwazi.
