Ngenkxaso yehlabathi jikelele kunye nokukhuthazwa kwezakhiwo ezenziwe kwangaphambili, ishishini lokwakha liye langena ngokuthe ngcembe kwixesha lemizi-mveliso, ngoko yintoni kanye kanye isakhiwo esakhiwe kwangaphambili?Ngamafutshane, izakhiwo ezenziweyo zifana neebhloko zokwakha.Amalungu ekonkile asetyenziswa kwesi sakhiwo alungiswa kwangaphambili kumzi-mveliso, aze ke asiwe kwindawo yokwakha ukuze axhonywe, adityaniswe aze adityaniswe ukuze enze eso sakhiwo.
Buyintoni ubudlelwane phakathi kwezakhiwo ezenziweyo kunye ne-MS sealant?
Ngenxa yokuba izakhiwo ezisele zilungisiwe zidityaniswe kumacandelo asele enziwe kumzi-mveliso, ngokuqinisekileyo kukho izikhewu ezithile phakathi kwamacandelo.Ukuzalisa ezi zithuba zendibano kubaluleke kakhulu.Okwangoku, kukho iintlobo ezintathu ze-high-performance sealants yokwakha kwimarike: i-silicone, i-Polyurethane kunye ne-polysulfide, i-MS sealant yahlukile nakweyiphi na kwezi zintathu.Yi-silicone-modified polyether sealant eyakhiwe njengelifa iimpawu ze-terminal silyl structure kunye ne-chain chain polyether bond structure, edibanisa iingenelo ze-polyurethane sealant kunye ne-silicone sealant ngokwemigaqo yokusebenza, lukhokelo olubalulekileyo kuphuhliso olutsha. sealants ekhaya nakwamanye amazwe.
Ke ziziphi iingenelo ze-MS sealant xa kuthelekiswa nezitywini zesakhiwo ezenziwe ngaphambili?
1.Umgangatho ophezulu wokubuyiswa kwe-elastic kunye nomthamo onamandla wokufuduka
Ngenxa yokuba ukudibanisa kwe-slabs yekhonkrithi kuya kukwandiswa, ukuchithwa, ukuguqulwa kunye nokufuduka ngenxa yokutshintsha kweqondo lokushisa, i-concrete shrinkage, i-vibration encinci okanye ukuhlaliswa kwesakhiwo, njl., ukwenzela ukuthintela i-sealant ekuqhekekeni kunye nokuqinisekisa ukuxhamla okukhuselekileyo nokuthembekileyo kunye nokutywinwa. yamalungu, i-sealant esetyenzisiweyo kufuneka Inomlinganiselo othile we-elasticity kwaye inokwandisa ngokukhululekileyo kunye nekhontrakthi kunye nokuvulwa kunye nokuvala i-deformation yokudibanisa ukugcina ukutywinwa kokudibanisa.Umthamo wokufuduka we-sealant kufuneka ube mkhulu kunokuhanjiswa okuhambelanayo komthungo webhodi.Ayiyi kukrazula kwaye yomelele ngexesha lokuguqulwa kwe-cyclic ephindaphindiweyo.I-Punctured, inokugcina kwaye ibuyisele ukusebenza kwayo kwasekuqaleni kunye nokumila.Emva kovavanyo, ireyithi yokubuyisela i-elastic, umthamo wokufuduswa kunye nemodyuli yokuqina ye-MS sealant zonke zigqithile kwiimfuno zomgangatho wesizwe, kwaye ineempawu ezilungileyo zoomatshini.
2. Ukumelana nemozulu okugqwesileyo
Kwi-JCJ1-2014 "IiMimiselo yobuGcisa yoLwakhiwo lweConcrete oluFakelweyo", kucaciswa ngokucacileyo ukuba izinto zokutywina ezikhethiweyo kwizakhiwo ezidibeneyo aziyi kuhlangabezana neemfuno zokusebenza komatshini ngaphandle kokuchasana nokucheba kunye nokwandiswa kunye nokuguqulwa kobuqhetseba, kodwa kwakhona ukuhlangabezana nokuxhathisa ukubola, manzi, Ukwakha iimfuno zokusebenza komzimba ezifana nokumelana nemozulu.Ukuba izinto eziphathekayo azikhethwanga ngokufanelekileyo, i-sealant iya kuqhekeka, ingaphumeleli ukufezekisa umphumo wokutywinwa, kwaye i-sealant iya kuphumelela, eya kuchaphazela ukhuseleko lwesakhiwo.Ubume be-MS sealant yi-polyether njengekhonkco eliphambili, kwaye ikwaqulethe amaqela e-silyl anamaqela asebenzayo okuphilisa.Inika umdlalo opheleleyo kwiinzuzo ze-polyurethane sealant kunye ne-silicone sealant, kwaye iphucula kakhulu ukuchasana kwemozulu ye-sealant.
3. ukupeyinta okuqinileyo, ukukhuselwa kwendalo kunye nokungangcoliseki
Ngenxa yokuba i-MS glue ineengenelo zazo zombini i-polyurethane sealant kunye ne-silicone sealant, isombulula iziphene ze-polysulfide sealant ezifana nesantya esicothayo sobushushu obuphantsi bokunyanga, ukuguga okulula kunye nokuqina, ukungabikho kokuqina, kunye nevumba elibukhali elibukhali;ngelo xesha, i-MS glue ayifani ne-silicone sealants, i-adhesive layer ilungele ukuvelisa i-oyile leachate engcolisa ikhonkrithi, ilitye kunye nezinye izinto zokuhombisa.Inobuhle bokupeyinta kunye nokukhuselwa kokusingqongileyo, okukhuthaza ngakumbi uphuhliso kunye nenkqubela phambili ye-prefabricated sealants yokwakha.
Ngokubanzi, izakhiwo ezenziwe ngaphambili ziyindlela yophuhliso lweemodeli zokwakha.Kuyo yonke inkqubo yokwakha eyakhiweyo, ukukhethwa kwe-sealant kuya kuba ngomnye wamacandelo abalulekileyo achaphazela ukhuseleko lwesakhiwo sonke esakhiweyo.I-Silicone modified polyether sealant sealant——I-MS sealant inomsebenzi ogqwesileyo obanzi kwaye iya kuba lolona khetho lwakho lubalaseleyo.
I-SIWAY izibophelele ekuboneleleni abathengi ngezinto ezizinzile nezithembekileyo ezikumgangatho ophezulu kunye neenkonzo zobugcisa ezilungiselelwe wena.Itekhnoloji yokuguqulwa kwe-silane ye-SIWAY iyaqhubeka nokubonelela ngezisombululo zobungcali zokutywinwa kwesakhiwo esenziwe kwangaphambili kunye nokudibanisa.Sijonge phambili ekusebenzeni nawe.Sikunye, siya kunceda uphuhliso olomeleleyo lwezakhiwo ezenziweyo emhlabeni.
