Lapho kukhona isifiso sokuthuthuka kudivayisi yakho siqu electronic, kubalulekile isitoko i nokunamathisela ngomthofu yensimbi, solder futhi rosin. Yiqiniso, ungakhohlwa mayelana nemininingwane isikimu ngokuqondile, kodwa sinesithakazelo kwesikwenzayo ekukhuliseni ikhwalithi yenqubo nokunamathisela ngomthofu. Yingakho sidinga rosin? On ke, thina manje nixoxe.
Kuyini rosin?
Kungenzeka uye waphawula ezitolo, okuhloswe ngaso ukudayiswa izingxenye ukudalwa imikhiqizo yayo, esobala izidakamizwa lwengilazi okungukuthi kuthi akufane nokwenzeka Amber njengoba ukubukeka kwakho nombala. Lokhu rosin zikaphayini. Ngokokuqala ngqá le nto itholiwe emzini waseGrisi ka isigcino, futhi ekuqaleni ngokuthi "resin kolofonskoy." Bona ekhishwe ke kusukela turpentine resin. It is etholakale ezilwaneni ezahlukene zikaphayini, buhlukaniswe turpentine kanye nezinye izinto oluyingozi esebenzisa namabhati umusi. Ngesikhathi esifanayo yonke ukungcola non-oluyingozi ahlanganisiwe. Ziphuzo zazihluzwa kwenziwa ngokusebenzisa pair kabani izinga lokubanda lalingu-degree angu-200. Lesi sibalo aliholeli noqhekeko of rosin.
yesimanjemanje
Manje rosin ingatholakala ziyacolwa zikaphayini izinkuni ngosizo kumakhemikhali awuketshezi ekhethekile noma ikhiqizwa uwoyela ubude noma i-cellulose. Kungakhathaliseki ukuthi iyiphi zilwane enjalo ahlukanisa
- Pine.
- Okude.
- Isizinda.
Modern amaphesenti rosin 60-90 siqukethe abietic acid resin, 1-12% we okunamafutha acid kanye compounds kokungathathi hlangothi (ezifana triterpenoids, diterpenoids futhi sesquiterpenoids). Ngeke ziyoncibilika ngamanzi, kodwa utshwala, elithi ether, benzene, acetone futhi kancane okubi kakhulu ukwedlula kaphalafini kungenzeka ukuba enze kanjalo. Ngezinye 40 degrees rosin iqala ukuthambisa, futhi ngezinye 100 isivele kwancibilika. Lapho izinga lokushisa ifinyelela degrees 250, ke amathumba. Uma sifaka amaminerali kanye udaba eziphilayo, uthola insipho. Uma chaza it in polyol, khona-ke uyoba ester rosin. Njengoba ubona, eziningi izicelo. Yiqiniso, into ephephile ukwenze lapho rosin isandla zikaphayini. Umenzi kumele aqinisekise ukuthi imikhiqizo ukuhlangabezana nazo zonke izidingo kwamazinga wombuso (kwakungekho ukungcola zangaphandle noma enye into).
izakhiwo
Bayodla ifa izici kangcono zikaphayini rosin. GOST 19113-84 kuqinisekisa ukuthi imikhiqizo yalesi aphoyintimenti ukuhlangabezana namazinga ikhwalithi kanye nokuphepha abantu ezisebenza ngayo. Uqala ukuthambisa 68 degree ukushisa. Libuye cishe akukho acid okunamafutha. Lokhu rosin ubhekwa impahla yemvelo ngokuphelele futhi imvelo. It has umbala amber. Isizinda kanye Talovaya rosin kubhekwe yokufakelwa. Ziyahlukahluka kuye, futhi kube nombala wako. Kodwa nakuba isikhona izindlela ezahlukene ukulungiselela, izakhiwo zabo abhekwa eduze yini iwumkhiqizo wemvelo, okuyinto rosin zikaphayini. Kakhulu ukuba khona isango ethuthukisiwe, okuyinto phakathi evele uma usebenzisa lo mklamo. Futhi rosin has detergency ezinhle futhi ifinyelela inhliziyo (i-ether kanye notshwala izixazululo) izakhiwo. Lesi sakamuva eyaholela ekusetshenzisweni yayo njengendlela agent ungangenisi amanzi. Ingase futhi isetshenziswe njengethuluzi lokubandlulula ingcina.
Isicelo practice
Isicelo main namuhla - ukusiza ngesikhathi nokunamathisela ngomthofu metal izingxenye. Ngakho, njengoba zikaphayini rosin nokunamathisela ngomthofu ecucuza okubonisa umphumela omuhle. Naphezu kweqiniso lokuthi kukhona nabaningi wokucwaninga ngamakhemikhali lanamuhla, isasetshenziswa electronics kanye nobunjiniyela bukagesi. Ngakho, umfanekiso oncibilikisiwe rosin zikaphayini ngaphandle kwezinkinga ongaqeda ungqimba oxide okungukuthi phezu izingxenye ukuba soldered. Okubalulekile ukuthi kunciphisa amaphaphu ebusweni the solder. Lokhu kwenza kube ngokulinganayo basakaza phezu indiza ukusebenza. Ukusetshenziswa ecucuza ucingo ngale ndlela kwandisa izinga solder esetshenziswa. liphinde kunomphumela ezithile okuvikela ahlukahlukene ambient umusi imvelo. Futhi, ukuze alondoloze ukuthandwa futhi nomthelela ukungathathi hlangothi ene-asidi. Lena sibonga kungenzeka ukusetshenziswa izinto zokusetshenziswa odabuka yemvelo. Ngakho-ke, nokunamathisela ngomthofu lungekho ukugqwala ngokuhamba kwesikhathi akukho zamanje ukuvuza. Ukubaluleka esithile salokhu ngesikhathi inhlangano yabantwana kagesi. Futhi, uphayini, Talovaya futhi rosin lingasetshenziswa kanye ethanol abahlanzekile isilinganiso 4 kuya ku-6 ukuthola ecucuza ketshezi. Sebenzisa rosin bangaze ababambisisa insimbi nokunamathisela ngomthofu okokuqala empilweni yami. Okokuqala, kudingeka zishise a Udosi, ugcobhoze kuyo ketshezi eqandisiwe. Babe kuthathwe solder, okuyinto isetshenziswa ebusweni solder nemininingwane. Uma kunesidingo, sebenzisa ithiphu nokunamathisela ngomthofu kumele lusatshalaliswe ngokulinganayo. Ngenxa yalokho, kufanele uthole mass Monolithic, ezokwenza ukuxhuma ndawonye konke kuyadingeka. Have isicelo kweminye imikhakha yomsebenzi womuntu. Ngakho, rosin is ngokwesiko esetshenziswa ukukuthinta izintambo zomculo ezinezintambo zomculo, sengathi ukuba bagcobe esimweni powder, kungenzeka ukuthola eliphezulu intuthu imiphumela.
isiphetho
Njengoba ubona, rosin kuyithuluzi eliphumelela kakhulu emikhakheni eminingi. Futhi ubuholi unethemba phakathi kwazo zonke izinhlobo zikaphayini zemvelo ithatha izidakamizwa. Uma ufisa ukwazi ngokuningiliziwe kuyini nokuthi rosin zikaphayini, GOST 19113-84 ingakusiza nale.
