ukuba irekhodi

isakhiwo abicah sealant ufana umxube viscous, nto leyo kakhulu ngokulitywina amalungu kunye neentanda, kuncanyatheliswe uphawu abaza kuzisebenzisa kunye iindawo ezahlukeneyo. Xa le mifanekiso ziyabandakanywa kwamanzi, bafumana ukhuseleko evela impembelelo embi nokufuma.

Eyona engundoqo iintlobo abicah sealant ukubunjwa

Cala abicah sealant zihlelwe yi licandelo nokwakheka. Ekwenziweni kwayo ungadibanisa izinto ezahlukeneyo. Ngokomzekelo, omnye plasticizer yenza umbandela ilastiki, ngoxa viscosity sithatha vulcanizer. Njengesiseko kuphuma irabha, kwaye ubenokuqina ubume uyayinikwa primer ngaphezulu.

Abalimi amandla kuye kwafezekiswa ngombhobho, kodwa umbala umxube uba emva ukongeza lokufaka. Cala abicah sealant isenokuba olunye-candelo okanye icandelwana-emibini. Uhlobo lokuqala ezininzi eziqhele ukusetyenziswa kwi ukulungiswa kunye nolwakhiwo, lo gama kwimixube-component ezimbini enzelwe ukusetyenziswa kweli shishini.

Ukuthengiswa zingabonakala obrak, acid kunye sealants cala. Eyokuqala ngumxube iinjongo ezizodwa, yaye njengoko neziseko zazo ezivelileyo amine. Ukuba kokuba compound kuni bubonakaliswe ileta "A", ngoko ufanele wazi ukuba sealant asidi, asinto ibe ngendleko ephantsi yaye ubhetyebhetye iyasetyenziswa. Xa lemveliso izenzo njengesiseko acetic inuka acid ephuma ngexesha Ukuqinisa kunobukhulu. A engxakini lwendibanisela enjalo ukungavumelani kunye nesinyithi nonferrous, ekubeni ukukhawulezisa inkqubo umhlwa. Akuyi Kucetyiswa ukuba basebenzise izinto emuncu sealants nezemarmore, kwakunye nezinto zesamente, leyo eziqulathe izithako obrak.

• nongo;
• fillers mechanical;
• extenders;
• fungicides.

Zombala zongezwa kwi imveliso, Noko ke, emva kokuba yaphuse umxube ayikho ezinemibala. Fillers zinika adhesion ngoomatshini kunye kumphezulu ubunzima. Xa kuziwa ezongeziweyo koomatshini, koko apha kufuneka ibandakanye ngetshokwe zwi uthuli. Extenders kwimeko ka sealants imvelaphi yendalo, kwaye ke kufuneka ukuba ukunciphisa viscosity ye abicah. Fungicides zibulala fungi kunye umngundo. Ukwandisa intsimi lokusetyenziswa kunokuba sealant cala, kuqwalaselwa uhlobo additive.

Izimvo olungathath'icala abicah Sealant

Cala abicah sealant na ezinye iimpawu ezikhethekileyo: kuba soft and elastic. Phezu kwako nje oku, ezisetyenziswa xa kusenziwa izinto ezomeleleyo kakhulu uhlobo lesilicon, zwi nesanti. Kwezi copolymers zenziwe, ezo inxenye. Abathengi cell okumbalwa usebenzisa sealants abicah cala, oko kukuthi, ukukwazi olule, iqondo eliphezulu namandla, uzinzo kwelanga, a adhesiveness ephakamileyo, ukumelana ubushushu, ukumelana neemeko zokusingqongileyo kunye biostability.

Amalungu athi ukukwazi olule ivumela ukusetyenziswa kwezi nemixube kwamalunga movable. Ngenxa iqondo eliphezulu adhesion, imixube ezinjalo ingasetyenziswa phakathi kwezakhi iglasi, iiseramikhi, isinyithi, iinkuni kunye zeplastiki. Emva omiswe, abicah sealant ngaphaya cala ukuba lungakhuseleki amacandelo ndlongondlongo zokucoca, ukanti kuphulukana iipropati yayo. Ukuba kukho iintlobo ubushushu-resistant ukuba uza kukwazi ukugcina iipropati zabo kweemeko kuluhlu lobushushu leyo iyahluka ukusuka -50 ukuya +300 ° C.

Ngenxa yokuba umxube data bangenele ngokugqibeleleyo ifuthe iimeko zangaphandle, zinokusetyenziswa kuphela ngaphakathi kodwa ngaphandle kwisakhiwo. Emva kokuba isicelo, awukwazi ukoyika ukuba sealant okanye iindawo ezikufutshane iya kuba iintsholongwane okanye umngundo.

ukubuyekeza ezimbi

Sanitary abicah Sealant a cala, uluvo yomsebenzisi, kunye neengxaki ezithile. Phakathi kwabo kumele ziphawuliwe:

• Ayikho efumankekayo bala;
• ngokwaneleyo adhesion eliphezulu amacwecwe nemxinwa ezinepolypropylene.

Ibala umgangatho sealant emva Ukuqinisa yayo akunakwenzeka xa umxube iqulethe isixa esikhulu kwezinto eziphilayo. Kodwa ke ukungabikho adhesion ibonakala kwaye phakathi iipleyiti, ezenziwe polyethylene, polycarbonate okanye fluoroplastic. Njengokuba abasebenzisi bathi isisombululo inokuba ukuthenga sealant ezibiza kakhulu, nto leyo ilungiselelwe ukusetyenziswa yobungcali.

Amagqabantshintshi brand "Moment" iimpawu cala abicah sealant

Xa uqhekeko le yokuqamba landiswa 200% kunye nobuninzi bayo ingahluka 0,98 ukuya 1.00 g / cm ^3. Kwenye zobude ikhulu ekhulwini modulus ngu 0.3 MPA. Lo mxube ivavanywa kakuhle ukunyakama, kwaye umboniso emva nokufumba kubushushu ka +23 ° C emva kwemizuzu eli-15.

Izinga Ukuqinisa angamashumi amahlanu ekhulwini ukufuma imalunga-2 mm ngosuku. Le abicah sealant emhlophe cala yenzelwe ngokulitywina nofakelo yezibuko, anoomatshini bokungenisa umbane. Akuyi Kucetyiswa ukuba usebenzise umxube okanye ilitye yendalo ukutywina akwariyam.
