Ngenkxaso kunye nokukhuthazwa kwezakhiwo ezenziwe kwangaphambili kwihlabathi liphela, ishishini lokwakha liye langena kancinci kancinci kwixesha lemizi-mveliso, ngoko ke yintoni kanye kanye isakhiwo esenziwe kwangaphambili? Ngamafutshane, izakhiwo ezenziwe kwangaphambili zifana neebhloko zokwakha. Izinto zekhonkrithi ezisetyenziswa kwisakhiwo zenziwa kwangaphambili kumzi-mveliso, emva koko zithuthwa ziye kwindawo yokwakha ukuze ziphakanyiswe, zifakwe kwaye zihlanganiswe ukuze zenze isakhiwo.
Luluphi ulwalamano phakathi kwezakhiwo ezenziwe kwangaphambili kunye ne-MS sealant?
Ngenxa yokuba izakhiwo ezenziwe ngaphambili zihlanganiswe ngezinto ezenziwe ngaphambili zefektri, ngokungathandabuzekiyo kukho izithuba ezithile zokuhlanganisa phakathi kwezinto. Ukuzalisa ezi zithuba zokuhlanganisa kubaluleke kakhulu. Okwangoku, kukho iintlobo ezintathu ze-sealants zokwakha ezisebenza kakuhle kwimarike: i-silicone, i-Polyurethane kunye ne-polysulfide, i-MS sealant yahlukile kuyo nayiphi na kwezi sealants zintathu. Yi-sealant ye-polyether eguqulwe yi-silicone efumana ngokwesakhiwo iimpawu zesakhiwo se-terminal silyl kunye nesakhiwo se-polyether bond esiphambili, esidibanisa iingenelo ze-polyurethane sealant kunye ne-silicone sealant ngokwemisebenzi, yindlela ebalulekileyo yophuhliso lwe-sealants ezintsha ekhaya nakwamanye amazwe.
Ngoko ke zithini iingenelo ze-MS sealant xa kuthelekiswa ne-sealants zezakhiwo ezenziwe kwangaphambili zemveli?
1.Izinga eliphezulu lokubuyisela amandla kunye nomthamo oqinileyo wokufuduka
Ngenxa yokuba iindawo ezidityanisiweyo zesamente ziya kwanda, zibhityaniswe, ziguquguquke kwaye zifuduke ngenxa yotshintsho lobushushu, ukuncitshiswa kwesamente, ukungcangcazela okuncinci okanye ukuhlala kwesakhiwo, njl.njl., ukuze kuthintelwe ukuba isitywini singaqhekeki kwaye kuqinisekiswe ukuba ibotshelelwe kwaye itywinwe ngokukhuselekileyo nangokuthembekileyo, isitywini esisetyenzisiweyo kufuneka sibe nomlinganiselo othile wokuqina kwaye sinokwandiswa ngokukhululekileyo kwaye sinciphe ngokuvuleka nokuvala kwesixhumi ukuze kugcinwe ukutywinwa kwesixhumi. Umthamo wokufuduka kwesitywini kufuneka ube mkhulu kunowokufuduka kwesixhumi sebhodi. Ayizukukrazuka kwaye ihlale ixesha elide ngexesha lokuguquguquka okuphindaphindiweyo. Ibhoboziwe, inokugcina kwaye ibuyisele ukusebenza kwayo kwasekuqaleni kunye nokuma kwayo. Emva kovavanyo, izinga lokubuyisela i-elastic, umthamo wokufuduka kunye ne-tensile modulus ye-MS sealant zonke zidlule kwiimfuno zomgangatho wesizwe, kwaye ineempawu ezilungileyo zoomatshini.
2. Ukumelana nemozulu okugqwesileyo
Kwi-JCJ1-2014 "Imimiselo yoBugcisa yeZakhiwo zeKhonkrithi eziSetyenzisiweyo", kucacisiwe ngokucacileyo ukuba izixhobo zokutywina ezikhethiweyo kwiindawo zokwakha aziyi kuhlangabezana neemfuno zokusebenza koomatshini kuphela ngaphandle kokuxhathisa ukucheba kunye nokukwazi ukuguquguquka kokwandiswa kunye nokubhitya, kodwa ziya kuhlangabezana nokuxhathisa ukubola, ukungangeni manzi, iimfuno zokusebenza komzimba njengokumelana nemozulu. Ukuba izinto azikhethwanga ngokufanelekileyo, i-sealant iya kuqhekeka, ingaphumeleli ukufezekisa isiphumo sokutywina, kwaye ne-sealant iya kusilela, nto leyo eya kuchaphazela ukhuseleko lwesakhiwo. Ulwakhiwo lwe-MS sealant yi-polyether njengekhonkco eliphambili, kwaye ikwaqulathe amaqela e-silyl anamaqela asebenzayo okulungisa. Inika ukudlala okupheleleyo kwiingenelo ze-polyurethane sealant kunye ne-silicone sealant, kwaye iphucula kakhulu ukumelana nemozulu kwe-sealant.
3. ukupeyintwa kakuhle, ukhuseleko lokusingqongileyo kunye nokungabinangcoliseko
Ngenxa yokuba iglu ye-MS ineengenelo ze-polyurethane sealant kunye ne-silicone sealant, isombulula iingxaki ze-polysulfide sealant ezifana nesantya sokunyanga esiphantsi kobushushu obuphantsi, ukuguga nokuqina okulula, ukungabikho kokuqina, kunye nevumba elibi elinamandla; kwangaxeshanye, iglu ye-MS ayizithandi ii-silicone sealants, umaleko we-adhesive uthambekele ekuveliseni i-leachate enamafutha engcolisa ikhonkrithi, amatye kunye nezinye izinto zokuhombisa. Inokupeyintwa kakuhle kwaye ikhusela okusingqongileyo, nto leyo ekhuthaza ngakumbi uphuhliso kunye nenkqubela ye-sealants zokwakha ezenziwe ngaphambili.
Ngokubanzi, izakhiwo ezilungisiweyo zezona ndlela ziphambili zophuhliso lweemodeli zokwakha. Kwinkqubo yonke yokwakha eyenziwe kwangaphambili, ukukhetha i-sealant kuya kuba yenye yezona ndawo zibalulekileyo ezichaphazela ukhuseleko lwesakhiwo sonke esenziwe kwangaphambili. I-silicone modified polyether sealant sealant——I-MS sealant isebenza kakuhle kakhulu kwaye iya kuba lolona khetho lwakho lubalaseleyo.
