Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
Ukukhula kwamandla okuqala kwe ukhonkolo wegwebu uyanensa, ngokuvamile ukufinyelela 30% yamandla okuklama ku 3 izinsuku, 50% yamandla okuklama ku 7 izinsuku, futhi 70% yamandla okuklama ku 15 izinsuku. Ngakho-ke, ukunakekelwa kusenesikhathi kukakhonkolo onegwebu kubaluleke kakhulu. Ngokuvamile, ngemva kokuthululwa kukakhonkolo onamagwebu, ukwelapha ngesikhunta kusetshenziswa kakhulu, futhi ukuchelela ukuphulukiswa kwengezwa ukuze kugcinwe ubuso bukakhonkolo obugwebu bumanzi. Isikhathi sokwelashwa asikho ngaphansi kwe-14d. Ungasebenzisi amanzi ngqo endaweni eveziwe yekhonkrithi yegwebu esanda kuthululwa. Ukuze kube lula, yonke inqubo yokuphulukisa ukhonkolo onegwebu ihlukaniswe izigaba ezimbili, ukwelashwa kokuqala kanye nokwelashwa okumanzi. Ukwelashwa kokuqala kufanele kuqale ngokushesha ngemva kokuthelwa ukhonkolo osanda kuxutshwa negwebu, futhi ukuphulukiswa okumanzi kuqala ngemva kokuba ukhonkolo usumisiwe ekugcineni.
1 Ukunakekela okujwayelekile
Ukugcinwa kukakhonkolo we-Foam kufanele kunake izici ezimbili zomswakama kanye nezinga lokushisa. Ukongiwa kwemvelo akukhona nje ukuchelela nokuthambisa kuphela kodwa futhi nokulawula ukushintsha kwezinga lokushisa kukakhonkolo. Ngenkathi ukwelapha okumanzi, kufanele kuqinisekiswe ukuthi awukho umehluko omkhulu phakathi kwezinga lokushisa elingaphezulu likakhonkolo onegwebu kanye nezinga lokushisa langaphakathi kanye nezinga lokushisa lomoya.. Ukuthatha izinyathelo ezibanzi zokulondoloza ukushisa kanye nokuchithwa kokushisa kungavimbela ukwehla kwezinga lokushisa kanye nokwehluka kwezinga lokushisa ekubeni kukhulu kakhulu..
Ukhonkolo wegwebu ngokuvamile ulapheka ngokufafaza amanzi noma ngokugcina amanzi noma umbozwe ngesihlabathi esimanzi namasaka amanzi. Ukhonkolo onegwebu othelwa esimweni sezulu esibandayo uvamise ukugcinwa uswakeme kusetshenziswa ukulethwa kwesitimu endaweni evalekile. Ukhonkolo onegwebu omanzisa ngaphansi kwelanga nezimo zokuvikela ilanga kuvame ukusebenza kangcono kunokufafaza amanzi endaweni esobala kakhonkolo onegwebu.. Ukulungiswa kwefilimu (ifilimu yepulasitiki engangeneki noma ifilimu elakhiwe i-ejenti yokwelapha) iyindlela enhle kakhulu yokwelapha yokufaka ukushisa lapho umthombo wamanzi unganele. Noma kunjalo, kufanele kuqashelwe ukuthi ubuso bukakhonkolo obunegwebu kufanele bube sesimweni esigcwele ngaphambi kokuba ifilimu ivalwe..
Ngemuva kokukhipha i-formwork noma ukususa isivikelo se-insulation, uma izinga lokushisa elingaphezulu lehla ngokuzumayo, ukhonkolo onegwebu ungase udale imifantu. Kuphela lapho izinga lokushisa lanoma iyiphi ingxenye yekhonkrithi enegwebu liyancipha kancane kancane, isivikelo singasuswa. Ukhonkolo onegwebu onomthamo omkhulu awukwazi ukupholiswa ngokushesha, ngoba uma kunomehluko wokushisa phakathi kwangaphakathi nangaphandle kukakhonkolo onegwebu, kunethuba eliphezulu lokuthi ukhonkolo onamagwebu phezu kwendawo ecishiwe uzoqhekeka. Lapho ukhonkolo wegwebu uthatha ukushisa okomile, amanzi anele kumele kwengezwe.
2 Ukunakekela endaweni eshisayo
Uma kuqhathaniswa nokhonkolo ojwayelekile, amandla ukhonkolo foamed isikhathi eside. Kodwa esikhathini esizayo, akufanelekile ukugcina ukhonkolo onegwebu ngokushisa okuphezulu. Ngokusho kobukhulu bengxenye, okuqukethwe usimende, isilinganiso se-water-binder, izimo zemvelo, nezimo ezishisayo, kuyadingeka ukuthatha izinyathelo ezilandelayo zokulawula izinga lokushisa lokukhonkolo elinegwebu ngesikhathi sokuphulukisa: (1) ukunciphisa izinga lokushisa lokuthululela ukhonkolo olugwetshiwe; (2) ukumboza Izinto ezisebenza kahle kakhulu zokufakwa kwe-thermal; (3) ukhonkolo onamagwebu kufanele uthululwe ekushiseni okuphansi; (4) indawo evulekile yokhonkolo osanda kuthululwa enegwebu kufanele imbozwe.
3. Izinga lokushisa eliphansi (izinga lokushisa elibi) ukugcinwa kwemvelo
Ukwelashwa kwemvelo kokhonkolo we-foam emazingeni okushisa aphansi kufanele kuhlanganiswe nefilimu yepulasitiki e-opaque noma kufafazwe ngoketshezi lokuphulukisa. Lapho ukwelapha ngaphansi kwezimo ezimbi zokushisa, ukuchelela akuvunyelwe. Ngemva kokuthela ukhonkolo onegwebu, kufanele imbozwe ngefilimu yepulasitiki kanye nezinto zokuvikela ezifana notshani noma utshani ukuze kuvinjwe ukhonkolo ekuqandiseni. Izingubo zokulala ezenziwe nge-glass fiber, irabha yesipontshi, i-cellulose, uboya bamaminerali, i-vinyl foam, futhi i-polyurethane foam iyasebenza kakhulu. Ezimweni zezulu ezibandayo, ukushisa okwengeziwe kuyadingeka ukuze kugcinwe izinga lokushisa 10 ℃ ~ 15 ℃, ukuze izinga lokushisa londle, ungasebenzisa amakhoyili okushisa, izifudumezi eziphathwayo noma isitimu ukunikeza ukushisa okudingekayo.
Ukufingqa isondlo kuzo zonke izimo ezishiwo ngenhla, ukulahlekelwa umswakama kukhonkolo enegwebu kufanele kugwenywe. Ukuqinisekisa ukulahleka kwamanzi ohlelweni lokushisa kwe-hydration kasimende okhonkolo onegwebu, imifantu yayibangelwa ukushisa okungalingani kokushisa kwe-adhesive’s hydration.
I-Cie-China.org ingumhlinzeki oholayo wezithasiselo zikakhonkolo wegwebu ohlinzeka nge-ejenti yokugwedla ukhonkolo, superplasticizer,isithuthukisi samandla kakhonkolo wegwebu kukhonkolo ongasindi, Amabhulokhi e-CLC. Uma ufuna i-ejenti ekhipha amagwebu, sicela ukhululeke Xhumana nathi.
