Imisebenzi eminingi yama-Sealants
Ama-sealant enza indima ebalulekile ekusebenzeni njengesithiyo ekulweni nomswakama, uthuli, namanye amakhemikhali ayingozi. Asetshenziselwa ukuqukatha uketshezi noma amagesi futhi ahlinzeke nge-coating ukuvikela izindawo emonakalweni. Ama-Sealants ayasebenza ku ukuvimbela amanzi izakhiwo kanye nokuhlinzeka ngokuvikelwa okushisayo, okuzwakalayo, kanye nomlilo.
Ukugcwalisa Izikhala kanye Nezindawo Ezibushelelezi
Ama-sealants asetshenziselwa ukugcwalisa izikhala kanye nokuqhekeka kwezakhiwo, ukuhlinzeka ngokunamathela ngokomzimba nokugcina ukusebenza okulindelekile kwesakhiwo. Zibuye zisetshenziselwe ukwenza izinto ezibushelelezi, zinikeze ukubukeka okucacile nokusebenzayo.
Ukwakhiwa kanye Nesicelo
Ama-sealants atholakala ngezindlela ezihlukahlukene zokwakheka, okuhlanganisa i-organic kanye nama-elastomers. Kulula ukuzisebenzisa futhi zinikeza ubulula nokuthembeka ekusetshenzisweni kwazo. Ama-sealants aklanyelwe ukuhlalisa ukunyakaza kwezakhiwo, ukuqinisekisa ukuthi agcina izakhiwo zawo zokuvala ngokuhamba kwesikhathi.
Izakhiwo Ezisebenzayo
Ama-Sealants ahlinzeka ngezinto eziningi ezisebenzayo, okuhlanganisa ukunamathela, ukuvimbela amanzi, nokuvikela umlilo. Asetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi izimboni zokwakha, zezimoto, kanye nezimboni zezindiza.
Izinsuku Zokuqala Zama-Sealants: Kusukela Kubumba Lwasendulo Kuya Ezigxivizini Zamazinyo Zanamuhla
Ukubeka uphawu bekuwumkhuba kusukela ezikhathini zasendulo, lapho izimpucuko zamazwe aseNtshonalanga zisebenzisa izinto ezihlukahlukene ukuze zivale izinto nezakhiwo. Nazi izibonelo:
- E-Indus Valley Civilization, abantu basebenzisa ubumba ukuze bavale amakhaya abo futhi bavimbele amanzi ukuthi angangeni.
- Emikhubeni yenkolo yasendulo, ukubekwa uphawu kwakusetshenziselwa ukugcina izinto ezingcwele nemibhalo iphephile emonakalweni noma ekuphazanyisweni.
- Ama-carbohydrate afana ne-wax ayesetshenziselwa ukuvala iziqukathi zokudla neziphuzo ukuze zihlale zintsha.
Ukubekwa uphawu Kwezempilo Zamazinyo
Ukubekwa uphawu sekusetshenziswe impilo yamazinyo amakhulu eminyaka, izimpucuko zakuqala zisebenzisa izinto ezahlukahlukene ukugcwalisa imigodi nemifantu emazinyweni. Nazi izibonelo:
- Ngekhulu leshumi nambili, ingxube yoju netshe eliyimpuphu yayisetshenziselwa ukugcwalisa imigodi nemifantu emazinyweni.
- NgeNkathi Ephakathi, ingcina yezinyosi yayisetshenziselwa ukuvala amazinyo nokuvimbela ukubola.
- Ekuqaleni kwawo-1900, odokotela bamazinyo basebenzisa ingxube yesiliva nethini ukuze bagcwalise imigodi nemifantu.
Ukuthuthukiswa Kwezinsimbi Zamazinyo Zanamuhla
Ama-dental sealants esimanje aqala ukuthuthukiswa ngeminyaka yawo-1960s njengendlela yokuvimbela ukubola kwamazinyo. Nazi ezinye zentuthuko ezibalulekile:
- Ngawo-1960, izinsimbi zamazinyo zenziwa nge-acrylic futhi kwakunzima ukuzibeka.
- Ngawo-1970, izinsimbi zokuvala amazinyo zenziwa ngensimbi okwakulula ukuyibeka futhi esebenza kangcono ekuvimbeleni ukubola.
- Namuhla, ama-dental sealants enziwe ngezinto zepulasitiki ezisetshenziswa ezinyo futhi ziqiniswe ngokukhanya okukhethekile.
Izinhlobo zama-Sealants: Umhlahlandlela Ophelele
Ama-sealants yizinto ezisetshenziswa kakhulu ekwakheni nasensizakalweni yokwakha ukuvimbela ukuhamba kwezinto ezithile noma izinguquko zesimo. Zenzelwe ukuvala izikhala ezinzima futhi zivimbele ukungena komoya, amanzi, noma ezinye izinto. Ama-sealants afika ngezinhlobo ezahlukahlukene, ngayinye ihloselwe umsebenzi othile noma umsebenzi othile.
Izinhlobo Ezijwayelekile zama-Sealants

Ama-Sealants vs Adhesives: Uyini Umehluko?
Ama-sealants kanye ne-adhesives yimikhiqizo emibili evamile yokwakha neyokwakha ehlukile ekubunjweni kwayo namandla. Izinamathiselo zenzelwe ukubamba izindawo ezihlangene, kuyilapho ama-sealant asetshenziselwa ukugcwalisa izikhala futhi amelane nokunyakaza okuhlobene kwezindawo ezisetshenziswa kuzo. Izinamatheliso ngokuvamile zinamandla kunama-sealant, kodwa ama-sealant ahlinzeka umhlangano ngokuguquguquka okukhulu kakhulu. Izinamathiselo zakhiwe ngamakhemikhali alaphayo futhi akhe isibopho esiqinile phakathi kwama-substrates amabili, kuyilapho ama-sealants engenawo amandla aphezulu okunamathela okunamathelayo.
Phatha Isikhathi nokubamba Amandla
Ama-sealants nama-adhesives ayahluka ngesikhathi sazo sokwelapha namandla okubamba. Izinamathiselo ngokuvamile zelapheka ngokushesha futhi zinamandla okubamba aphezulu kunama-sealant. Ama-sealants, ngakolunye uhlangothi, ahlinzeka ngokuguquguquka okukhulu futhi angamelana nokunyakaza okuhlobene kwezindawo. Uma ukhetha phakathi kwama-sealant nama-adhesives, kubalulekile ukucabangela uhlelo oluthile kanye nokusebenza okufunayo.
Izincomo Zomkhiqizi
Kubalulekile ukulandela izincomo zomkhiqizi lapho ukhetha phakathi kwama-sealants nama-adhesives. Izinto ezihlukene zidinga izinhlobo ezahlukene zama-sealant nama-adhesives, futhi ukusebenzisa umkhiqizo ongalungile kungabangela ukuntuleka kokunamathela noma ukusebenza. Ezinye izinto zingadinga i-adhesive ephezulu, kanti ezinye zingadinga i-sealant eguquguqukayo. Ukukhetha kahle ama-sealants kanye nama-adhesive kubalulekile empumelelweni yanoma yisiphi isakhiwo noma iphrojekthi yokwakha.
Isiphetho
Ngakho-ke, yilokho okushiwo i-sealant nokuthi isetshenziswa kanjani. Ungumkhiqizo omuhle kakhulu wokuvala imifantu nokuvikela indawo ekulimaleni, futhi ususetshenziswe amakhulu eminyaka yizimpucuko zasendulo nezanamuhla. Kufanele nje ukhumbule ukusebenzisa i-sealant efanele ngomsebenzi ofanele, futhi usulungele ukuhamba. Ngakho-ke, ungesabi ukuzama!
