NgoJulayi ukuya kuSeptemba lixesha lonyaka elinobushushu obuphakathi kunye nemvula eninzi. Ngenxa yeempawu zendalo zepeyinti ephuma emanzini yabantwana, indawo yobushushu obuphezulu izisa imiqobo ethile kulwakhiwo lwepeyinti yabantwana, kunye nothotho lwepeyinti yepeyinti yepeyinti efana nepinhole, i-crack, i-edge shrinkage, i-flow hanging, i-adhesion kunye nokunye kulula. ukuba kwenzeke kwinkqubo yokwaleka. Ngenxa yeengxaki ezingentla zabantwana bepeyinti yamanzi kwixesha eliphezulu lokushisa, ukwenzela ukuba kuqinisekiswe umphumo wokugubungela, makhe sibone indlela ipeyinti yamanzi yabantwana eyakhiwe kwiqondo lokushisa eliphezulu?

1. Xa utshiza, i-1/3 okanye i-1/4 yomgca olandelayo kufuneka icinezelwe ukuphepha ukuvuza. Xa utshiza ipeyinti yokumisa ngokukhawuleza, isitshizi kufuneka sitshizwe ngokulandelelana, umphumo wokutshiza awufanelekanga.

2. Umgama phakathi kombhobho kunye nomphezulu wento ngokuqhelekileyo ngu-30-40 cm. Isondele kakhulu ukuwisa ngokulula; Kude kakhulu, inkungu yepeyinti engalinganiyo, ukugalela lula. Umbhobho ukude kumphezulu wento, kwaye inkungu ethe saa endleleni inokubangela inkunkuma. Umgama kufuneka ulungelelaniswe ngokohlobo lokutyabeka, i-viscosity kunye noxinzelelo. Umgama wokutshiza wepeyinti yokomisa kancinci unokuba mde kancinane, kwaye umgama wokutshiza wepeyinti yokomisa ngokukhawuleza ungasondela. Xa i-viscosity iphezulu, ingaba kufuphi; Xa i-viscosity iphantsi, ingaba ngaphezulu. Kuxinzelelo oluphezulu, umgama unokuba ngaphezulu, kuxinzelelo oluphantsi, umgama ungasondela; Ukusondela kancinci, kuncinci, uhlengahlengiso oluncinci phakathi kwe-10 mm kunye ne-50 mm, ukuba ngaphaya kolu luhlu, kunzima ukufumana ifilimu efunekayo.

3. Umpu wokutshiza unokunyuka, ezantsi, ekhohlo nasekunene. Baleka ngesantya se-10-12m/min ngokulinganayo, kwaye umbhobho kufuneka ujolise kumphezulu wento ukunciphisa ukutshiza okuthambekele. Xa utshiza kuzo zombini iziphelo zobuso bento, isandla esibambe i-trigger yompu wokutshiza kufuneka sikhululwe ngokukhawuleza ukunciphisa inkungu yepeyinti, kuba iziphelo ezimbini zomphezulu wento ngokuqhelekileyo kufuneka zitshizwe ngokuphindwe kabini, ethanda ukuhamba.

4. Nika ingqalelo kwicala lomoya xa utshiza ipeyinti kwindawo evulekileyo yangaphandle (engafanelekanga umoya onamandla). Umsebenzisi kufuneka ame kwicala lomoya ophantsi ukuze athintele inkungu yepeyinti ukuba ingavutheli kwifilimu yepeyinti elungiselelwe, eya kwenza i-particle surface ibe mbi.

5. Ukutshiza ngokulandelelana: kunzima ngaphambi kokuba lula, ngaphakathi emva kwangaphandle. Okokuqala ukuphakama emva kokuphantsi, indawo yokuqala encinci, emva kwendawo enkulu. Ngale ndlela, ukutshiza kwamanzi akuyi kutshiza kwifilimu yepeyinti yokutshiza, konakalise ukutshiza ifilimu yepeyinti.

Ukwakhiwa kwepeyinti yamanzi kubantwana ngumsebenzi ocokisekileyo kwaye ufuna iimeko ezifanelekileyo zokusingqongileyo. Ehlotyeni, iqondo lokushisa liphezulu, imozulu itshintsha kakhulu, iindudumo zininzi, ukukhanya kunamandla. Ezi mpawu zeklimati zinempembelelo enkulu kubushushu, ukufuma, ukukhanya, ukungena komoya, njl njl. Umgama phakathi kwepeyinti ephuma emanzini yabantwana kunye nendawo efanelekileyo yokwakha inkulu kancinane, ekulula ukuyichaphazela ukwakhiwa.

Ngoko ukuba sifuna ukuba ipeyinti ephuma emanzini yabantwana ibe nefuthe elingcono lokusetyenziswa, kufuneka sinikele ingqalelo kumxholo ochaphazelekayo, singumvelisi wepeyinti ephuma emanzini yabantwana, ukuba ufuna ukwazi ukuba yintoni ipeyinti yamanzi yabantwana, unokuqhagamshelana nathi. Siza kukuxelela ngakumbi ngayo kwimiba eyahlukeneyo.
