Ngokusekelwa nokukhuthazwa kwezakhiwo ezenziwe kusengaphambili emhlabeni wonke, imboni yokwakha iye yangena kancane kancane esikhathini sezimboni, ngakho-ke siyini ngempela isakhiwo esenziwe kusengaphambili? Kalula nje, izakhiwo ezenziwe kusengaphambili zifana namabhulokhi okwakha. Izingxenye zekhonkrithi ezisetshenziswa esakhiweni zilungiswa kusengaphambili efektri, bese zithuthwa ziye endaweni yokwakha ukuze ziphakanyiswe, zihlanganiswe futhi zihlanganiswe ukuze zakhe isakhiwo.
Buyini ubudlelwano phakathi kwezakhiwo ezilungisiwe kanye ne-MS sealant?
Ngenxa yokuthi izakhiwo ezenziwe kusengaphambili zihlanganiswe ngezinto ezenziwe kusengaphambili zasefektri, ngokungenakugwenywa kunezikhala ezithile zokuhlangana phakathi kwezingxenye. Ukugcwalisa lezi zikhala zokuhlangana kubaluleke kakhulu. Njengamanje, kunezinhlobo ezintathu zezivikelo zokwakha ezisebenza kahle kakhulu emakethe: i-silicone, i-Polyurethane kanye ne-polysulfide, i-MS sealant ihlukile kunoma iyiphi yalezi zivikelo ezintathu. Kuyisivikelo se-polyether esiguqulwe nge-silicone esizuza ngokwesakhiwo izici zesakhiwo se-terminal silyl kanye nesakhiwo se-polyether bond se-chain main, esihlanganisa izinzuzo ze-polyurethane sealant kanye ne-silicone sealant ngokusebenza, kuyisiqondiso esibalulekile sokuthuthukiswa kwezivikelo ezintsha ekhaya nakwamanye amazwe.
Ngakho-ke yiziphi izinzuzo ze-MS sealant uma kuqhathaniswa ne-sealants yesakhiwo esenziwe kusengaphambili?
1.Izinga eliphezulu lokululama elinwebekayo kanye nomthamo oqinile wokufuduka
Ngenxa yokuthi amalunga e-concrete slabs azokhula, anciphe, aguquke futhi ashintshe ngenxa yokushintsha kwezinga lokushisa, ukuncipha kwekhonkrithi, ukudlidliza okuncane noma ukuhlala kwesakhiwo, njll., ukuze kuvinjelwe i-sealant ukuthi ingaqhekeki futhi kuqinisekiswe ukubopha okuphephile nokuthembekile nokuvalwa kwamalunga, i-sealant esetshenziswayo kumele ibe nezinga elithile lokunwebeka futhi ingakhula futhi inciphe ngokukhululeka ngokuguqulwa kokuvulwa nokuvalwa kwe-joint ukuze kugcinwe ukuvalwa kwe-joint. Amandla okufuduka kwe-sealant kumele abe makhulu kunokususwa okuhlobene komthungo webhodi. Ngeke idabuke futhi iqine ngesikhathi sokuguqulwa okuphindaphindiwe kwe-cyclic. Uma ibhoboziwe, ingagcina futhi ibuyisele ukusebenza kwayo kwasekuqaleni kanye nesimo sayo. Ngemuva kokuhlolwa, izinga lokubuyisa i-elastic, amandla okufuduka kanye ne-tensile modulus ye-MS sealant konke kudlule izidingo ezijwayelekile zikazwelonke, futhi inezakhiwo ezinhle zemishini.
2. Ukumelana nesimo sezulu okuhle kakhulu
Ku-JCJ1-2014 "Imithethonqubo Yobuchwepheshe Yezakhiwo Zekhonkrithi Ezilungisiwe", kushiwo ngokusobala ukuthi izinto zokuvala ezikhethiwe zamajoyinti okwakha akumele zihlangabezane nezidingo zokusebenza kwemishini kuphela ngaphandle kwamakhono okumelana nokusika kanye nokwanda kanye nokuguqulwa kokugoba, kodwa futhi zihlangabezane nokumelana nokubola, ukungangenwa kwamanzi, izidingo zokusebenza ngokomzimba kwesakhiwo njengokumelana nesimo sezulu. Uma izinto zingakhethwanga kahle, i-sealant izoqhekeka, yehluleke ukufeza umphumela wokuvala, futhi ngisho ne-sealant izohluleka, okuzothinta ukuphepha kwesakhiwo. Isakhiwo se-MS sealant siyi-polyether njengeketanga eliyinhloko, futhi siqukethe namaqembu e-silyl anamaqembu asebenzayo okwelapha. Inikeza ukudlala okugcwele izinzuzo ze-polyurethane sealant kanye ne-silicone sealant, futhi ithuthukisa kakhulu ukumelana nesimo sezulu kwe-sealant.
3. ukupendwa kahle, ukuvikelwa kwemvelo kanye nokungabi nokungcola
Ngenxa yokuthi i-MS glue inezinzuzo ze-polyurethane sealant kanye ne-silicone sealant, ixazulula ukushiyeka kwe-polysulfide sealant njengokusheshisa kokupholisa okuphansi, ukuguga nokuqina okulula, ukuntuleka kokuqina, kanye nephunga elinamandla elinomunyu; ngesikhathi esifanayo, i-MS glue ayiwathandi ama-silicone sealants, ungqimba lwe-glue luvame ukukhiqiza i-leachate enamafutha engcolisa ukhonkolo, itshe nezinye izinto zokuhlobisa. Inokupendwa okuhle kanye nokuvikelwa kwemvelo, okukhuthaza kakhulu intuthuko kanye nenqubekela phambili yama-sealants ezakhiwo ezenziwe ngaphambilini.
Ngokuvamile, izakhiwo ezilungisiwe ziyinkambiso yokuthuthukiswa kwamamodeli okwakha. Kuwo wonke uhlelo lwezakhiwo ezilungisiwe, ukukhetha i-sealant kuzoba enye yezindawo ezibalulekile ezithinta ukuphepha kwesakhiwo sonke esilungisiwe. I-silicone modified polyether sealant sealant——I-MS sealant isebenza kahle kakhulu futhi izoba yisinqumo sakho esingcono kakhulu.
I-SIWAY izibophezele ekuhlinzekeni amakhasimende ngezinto zokwakha ezisezingeni eliphezulu nezizinzile kanye nezinsizakalo zobuchwepheshe ezenziwe ngokwezifiso. Ubuchwepheshe bokuguqulwa kwe-silane be-SIWAY buyaqhubeka nokuhlinzeka ngezixazululo zobungcweti zokubopha nokubopha izakhiwo ezenziwe kusengaphambili. Silangazelela ukusebenza nani. Sisonke, sizosiza ekuthuthukisweni okunamandla kwezakhiwo ezenziwe kusengaphambili emhlabeni.
