Ukusebenzisa i-sealant bead akwenzi nje kuphela ukuthi ibukeke ihlanzekile. Kuhlanganisa i-sealant ibe yi-joint, kukhiphe umoya futhi kuqinisekiswe ukuthintana okugcwele ne-substrates. Le nqubo ibalulekile ukuze kuvinjwe amanzi.

Icebiso Lobungcweti: Finyelela Ukuqeda Okungenaphutha
Ochwepheshe basebenzisa indlela ethile yokuhlanganisa okugobile kahle. Baqala ngokufaka induku yokusekela ukulawula ukujula kwe-sealant. Bese, bafaka i-masking tape emaphethelweni ahlangene ukuze bahlanze imigqa. Ngemva kokufaka i-bead eqhubekayo ye-sealant, basebenzisa induku yamathuluzi ukucindezela i-sealant ibe yisimo esigobile. Ukususa i-tape ngokushesha kushiya unqenqema oluqinile nolubukhali.

Ukuqonda Izikhathi Zokwelapha

Ukubekezela kuyingxenye ebalulekile yenqubo yokuvala. Ama-polyurethane kanye nama-hybrid polymer sealant aphilisa umswakama, okusho ukuthi athembele emswakama womoya ukuze aqine. Izimo zemvelo zithinta ngqo ukuthi lokhu kuthatha isikhathi esingakanani. Amazinga okushisa aphezulu kanye nomswakama omkhulu kuzosheshisa inqubo yokupholisa. Ngakolunye uhlangothi, amazinga okushisa abandayo nomoya owomile kungayinciphisa kakhulu ijubane. Hlola njalo ishidi ledatha lobuchwepheshe lomkhiqizo ukuze uthole izikhathi ezithile zokupholisa kanye namazinga okushisa okusetshenziswa ukuze ugweme ukwehluleka kwangaphambi kwesikhathi.

Ochwepheshe batholaizivalo ze-polymer ezihlanganisiweziyindlela engcono kakhulu kune-Silicon Sealant Engangeni Manzi ejwayelekile yezivalo eziningi ezisetshenziswa kabanzi. Zinikeza ukupendwa okuhle kakhulu nokuqina. Ngezicelo ezisindayo, ezihamba kakhulu, noma zesakhiwo, izivalo ze-polyurethane zihlala ziyisinqumo esinamandla. Ukukhetha umkhiqizo ofanele kuqinisekisa umphumela ophumelelayo nohlala isikhathi eside.

Ukuhlolwa Kokugcina
Funda njalo ishidi ledatha lobuchwepheshe lomenzi. Lesi sinyathelo siqinisekisa ukuhambisana nezinto ezithile kanye nezidingo zephrojekthi ngaphambi kokuqala umsebenzi.

Imibuzo Evame Ukubuzwa

Ngingayisebenzisa yini i-polyurethane sealant endlini yami yokugezela?

Ochwepheshe bavame ukuncoma ama-polymer ahlanganisiwe ezindlini zangasese. I-polyurethane inamandla kakhulu kodwa ingaba nephunga elinamandla ngesikhathi sokwelashwa kwayo. Ama-sealant ahlanganisiwe anikeza ukuvikela amanzi okuhle kakhulu futhi avame ukufaka ukumelana nesikhunta kanye nomkhuhlane impilo yonke, okwenza kube ukukhetha okuhle ezindaweni ezimanzi zangaphakathi.

Uyini umehluko omkhulu phakathi kwe-hybrid kanye ne-polyurethane sealants?

Ama-polyurethane sealant anikeza amandla aphezulu kakhulu okusebenza kwemishini emisebenzini yokwakha. Ama-polymer ahlanganisiwe anikeza ukusebenza okuhle kakhulu. Ahlanganisa amandla amahle nokumelana okuhle kakhulu kwe-UV kanye nokupendwa, okwenza abe nezimo eziningi kumaphrojekthi okuvala ajwayelekile.

Ngingayisusa kanjani i-polyurethane endala noma i-hybrid sealant?

Ukususa kudinga inqubo enezinyathelo ezimbili. Okokuqala, ochwepheshe basika futhi bakhuhle ingxenye enkulu yesivikelo esidala ngommese owusizo noma ithuluzi elikhethekile. Bese, basebenzisa isinyibilikisi samakhemikhali esenzelwe izivikelo ukuze zithambe futhi zisuse noma yiziphi izinsalela ezisele.

Inothi Lokuphepha:Hlala usebenza endaweni enomoya omuhle futhi ugqoke izimpahla zokuphepha ezifanele, okuhlanganisa amagilavu ​​​​nokuvikela amehlo, uma usebenzisa izinyibilikisi zamakhemikhali.

Ingabe ama-polymer ahlanganisiwe aphephile ukuze asebenzise umoya wangaphakathi?

Yebo, ama-polymer ahlanganisiwe ayisinqumo esihle kakhulu sokusetshenziswa ngaphakathi. Akhiwe ngaphandle kwama-isocyanate futhi anokukhishwa okuncane kakhulu kwe-Volatile Organic Compound (VOC).
