Kwesinye isikhathi kunesimo lapho udinga ukupenda amawindi epulasitiki asevele efakiwe. Ungazenza ngokwakho noma ucele usizo enkampanini ekhethekile. Manje kuneziphakamiso eziningi zalolu hlobo, ngakho-ke uma kungekho okuhlangenwe nakho kokupenda kwemisebenzi nesifiso sokuhlola, le yindlela elula yokuphuma. Ukuphendukela enkampanini, uthola iwindi elidwetshwe nesiqinisekiso sokuhlanganiswa okusetshenzisiwe. Ukwenza umsebenzi ngokwakho, uthola okuhlangenwe nakho okubaluleke kakhulu. Labo abaye banquma ukupenda izandla zabo bazosiza ekufundeni ubuchwepheshe, kanye nohlu lwezinto zokwakha nemishini edingekayo kulokhu.
Ingcindezi ephansi yokufafaza isibhamu
Izinto zokwakha nemishini
Ngaphambi kokupenda udinga ukushebelwa ezintweni ezilandelayo:
- i-punifier yephrofayili ye-PVC;
- Upende we-acrylic we-water-dispersion;
- ukupenda tape;
- ifilimu elivikelayo.
Imishini izodinga isibhamu esiphansi sokufafaza nge-nozzle 1.2-1.4 μm, hlunga (100 μm) kanye ne-Viscometer.
Umkhandlu
Isibhamu akudingekile ukuthenga, le mishini ingaqashwa. Ukukhetha imodeli, cabanga ukuthi ingcindezi yokusebenza ngesikhathi sombala we-PVC ingu-2-3 umoya.
I-visecometer yasendlini
Kungani udinga i-visecometer?
Ukuthola ukumbozwa kwekhwalithi ephezulu yephrofayili, udinga ukuletha upende ekuboniseni kokusebenza. Uma kukhulu kakhulu - isikhathi sokusoma siyanda, kepha okubi kakhulu - ukunamathela ngephrofayli yewindows kuwohloka. Uma kwenzeka upende we-staining kakhulu, sithola ungqimba oluncane kakhulu. Uma kunopende onjalo ukufaka isendlalelo esikhulu, kunikeza izinga eliphakeme le-shrinkage.
Ukufuya upende "esweni" ngokubala iphrofayili yepulasitiki akuwona umqondo omuhle kakhulu, njengoba kubaluleke kakhulu ukuthola ungqimba olunamakhanda. Ukukala ukubonakala, kungcono ukusebenzisa i-Viscometer PT-246 bese usebenzisa i-nozzle nge-6 mm. Isikhathi sokuphelelwa yisikhathi sokwelulama kwe-acrylic upende we-PVC sisuka kumasekhondi angama-25 kuye kwangama-30.
Isihloko ngesihloko: Ungasibeka kanjani uthango kusuka kugridi yamaketanga
Sebenzisa le divayisi ilula impela.
- I-nozzle efiselekayo iyasungulwa (ithuluzi lithengiswa liphelele ngama-nozzles amathathu osayizi abahlukahlukene).
- Upende uthululwa esitsheni (kuze kube selebula).
- Ngosizo lwe-stopwatch, isikhathi saso silinganiswa.
- Uma inani liyadingeka ngokwengeziwe - kwangezwa amanzi alungiselelwe futhi ukulinganisa kwenziwa futhi.
Ukulinganisa ukubonwa kopende nge-viscometer
Umsebenzi wokulungiselela
Ngaphambi kokubala egumbini lapho kuzokhiqizwa khona, udinga ukuvikela ngodonga lwefilimu, phansi kanye nophahla. Ifilimu lihlelwe ngosizo lokupenda. Ivala nengilazi yewindi nemithambeka. Kufanele yenziwe ngokucophelela futhi kahle. Emva kwalokho, iphrofayili uqobo iyalungiswa. Kufanele ihlanzwe uthuli nezinye izinhlayiya ezincane, bese icubungula ihlanzekile. Akunakwenzeka ukunganaki lesi sigaba, ngoba ihlanzekile futhi isusa ukucindezelwa okulo. Okulandelayo, ungalungiselela upende - ubheme, ulethe ekuboneni okufiselekayo nesihlungi.
Umkhandlu
Kufanele kukhunjulwe engqondweni ukuthi ngemuva kokupenda kokubhala kunesikhathi sokusebenza. Kungamahora ama-2-4. Uma imininingwane enjalo ingafakwanga ku-Ibul, udinga ukucacisa lapho uthenga.
Ukufaka i-flap esusiwe yefasitela lepulasitiki
Iphrofayili yokubala
Lapho kwenziwa wonke umsebenzi wokulungiselela, ungaqhubekela ekusebenziseni upende ewindini. Kungcono ukwenza lo msebenzi emazingeni okushisa asekamelweni (+ 20-25 º Yize abanye abakhiqizi be-Peakers bavuma ukuthi kungenzeka bafake izicelo kusuka ku-+5 ºс, kungcono kungcono kutsi ungalingeli, njengokwehlisa izinga lokushisa, kubikhe kumiswa. Amathuluzi wokupenda namathuluzi kufanele abe yizinga lokushisa elifanayo. Uma zilethwa egumbini elibandayo, udinga ukulinda kancane (cishe ihora).
Umbala wenziwa usebenzisa isibhamu sokufafaza. Sinikeza izeluleko ezithile zokusebenzisana nayo.
- Ukuxhuma isifutho ku-compressor, kufanele kukhunjulwe ukuthi ukushisa kwe-hose kufanele kube ngakwesokunene ukungaphazamisi umsebenzi.
- Lesi sibhamu siyalulekwa ukuthi sigcine ema-engeli angakwesokudla kohlaka lwewindi, ukuhambisa epulangwe ngejubane elifanayo ukuthola umhlanga.
- Kungcono ukuqala ngokucutshungulwa kwezindawo ze-angular, bese udlulela ekutayelweni okuyinhloko. Ungaqala kokubili ngenhla nangaphansi.
Isihloko ngesihloko: Ungayifaka kanjani izimpumputhe ezimile egumbini. Amathiphu wokufaka.
Ukufaka upende, cabanga ukuthi ubukhulu bengqimba kufanele babe ngaphakathi kwama-60-100 μm. Ungqimba onowomile onjalo okomisa amahora angu-8-9, ngemuva kwamahora ayi-12 sekuvele kucubungule amanzi. I-polymerization ephelele yenzeka ezinsukwini ezi-5.
Ngakho-ke, amawindi wensimbi epulasitiki alula, kepha ukunakwa okuningi kudinga isigaba sokulungiselela kanye nokukhethwa kokusungula. Uma uthatha umsebenzi ngokungathi sína futhi konke kwenziwa ngendlela efanele, ungenza umnikelo wakho kumklamo ovumelanayo wekamelo.
