Muva nje, uSteven uthole impendulo evela kwamanye amakhasimende: amandla akho okunamathela awalungile, awaqinile, azoba curly ngemva kobusuku obubodwa.Ingabe izinga lokunamathela alilungile?

Ekuqaleni, uSteven ucabanga ukuthi ukukhiqizwa kwefekthri akuqinile, isilinganiso asanele. Ngesinye isikhathi, ifektri yavalwa ukuze ihlolwe. Cabanga ukuthi kungani lokhu kwenzeka.

Ngokuvela kwalolu hlobo lwenkinga ngokulandelana okusheshayo muva nje, futhi kukhawulelwe ezindlini zokuphrinta ezimbalwa ezizovela, ikhasimende likhiqiza ibhodlela lokupakisha.Futhi lokho kungenze ngacabanga.

 

Okokuqala, ake sihlaziye umlandu: ukunamathela

Ukwakheka kwe-adhesive ngokuvamile ihlukaniswe yaba izinhlobo ezimbili: Ingcina yamanzi B ingcina encibilikayo eshisayo.

Iglue yamanzi, akudingekile ukusho, iwuhlobo olunamanzi njenge-solvent noma i-dispersion medium glue, ukunamathela kokuqala kweglue akukuhle kangako, yilokho okubiza ngokuthi isitika ekuqaleni akunamandla kangako, lokhu kungenxa yezakhiwo zeglue, ingcina ayinamandla kakhulu ekuqaleni, kodwa ngokukhula kwesikhathi, ilebula izoba namandla ngokwengeziwe, uma isikhathi eside, i-viscous eyengeziwe.

I-adhesive encibilikayo eshisayo, abantu abadala abanyathelisayo kufanele bazi kangcono kunami, iwuhlobo lwezinamathiselo zepulasitiki, izinga lokushisa elithile elishintshashintshayo futhi lishintshe isimo salo somzimba, lisetshenziswe le mibhalo yeglue, ukunamathela okuqinile kokuqala, ukunamathisela kuyisiqalo kunamandla kakhulu, kodwa ngokunyuka kwezinga lokushisa nesikhathi, i-viscosity iyancipha kancane kancane, le glue ithonywa ukushisa nesikhathi.

Ngakho-ke, ingoba ngisebenzise isitikha esisekelwe emanzini, okwenza ilebula inganamatheli ngokwanele?

Eqinisweni, akuqinisekile, ake sibheke, siyini isimo esijwayelekile selebula viscosity akwanele, icala lezinga?

1. Amabhodlela epulasitiki.

Ngokujwayelekile khetha amakhasimende elebula lezandla, angabakhiqizi, ukubumba umjovo wepulasitiki, phansi komugqa wokukhiqiza, sekuzoqala ukulebula.

Ake sibheke ikhemikhali ebalulekile ekukhiqizeni amabhodlela epulasitiki abunjwe ngomjovo: I-ejenti yokukhishwa.

Iyini i-ejenti yokukhulula?

Kuyinto esebenzayo phakathi kwesikhunta kanye nomkhiqizo ophelile.Ama-agent okukhishwa aphikisana namakhemikhali futhi awancibiliki lapho ethintana nezingxenye zamakhemikhali zama-resin ahlukene, ikakhulukazi i-styrene nama-amines.I-agent yokukhishwa nayo inokumelana nokushisa kanye nezindawo zokucindezeleka, akulula ukubola noma ukugqoka;

Izakhiwo: Kuwuphawu oluhlanganisa ubuso olusetshenziswa ezindaweni ezimbili ezinamathelana kalula. Kwenza izindawo ezingaphezulu zikhiphe kalula, zibe bushelelezi futhi zihlanzeke.

2, i-varnish

Eyaziwa nangokuthi lapho amanzi, inhlaka iyingxenye yefilimu eyinhloko kanye nokwakheka kwe-solvent kapende.Ngenxa yokuthi i-coating ne-besmear isobala, futhi shayela ukunamathela obala ngokufanele.Inamekwe phezu kwento, yomile ukuze yakhe ifilimu ebushelelezi, ibonisa ingaphezulu lokuthungwa kwasekuqaleni.

Properties: Ungqimba olubushelelezi oluvikelayo phezu kwento.

3. Abanye

Imikhiqizo eqediwe esanda kunyatheliswa izofafazwa nge-talcum powder nezinye izinto, njengekhabhinethi yefektri nayo izofafazwa ngesisombululo sokuvikela uwoyela.

Lezi zimo zizovela ukunamathisela okunamathelayo akuqinile.

Ukwakheka kwamakhemikhali kweglue ngokuvamile kuqukethe i-vinyl acetate, i-varnish noma i-ejenti yokukhulula ngokuvamile iqukethe i-xylene namafutha a-silicone.Enye yalezi zingxenye izodiliza iglue, kanti enye ngeke isabele nayo.Ngaphezu kwalokho kufanele kunamathiselwe ebusweni bento kukhona olunye uthuli noma uketshezi oluvikelayo, ukuze i-adhesive kanye nento ayikwazi ukunamathela ngokugcwele.

Kuphinde kwavela inkinga esihlala sikhathazeka ngayo: isitika asinamatheli

Pho sibhekana kanjani nalesi simo?

Kulula: hlanza indawo.
