Rosin - yinto izinto umdla kakhulu

Rosin - ke amorphous, into ntlanzi ukuba isakhiwo yiglasi kunye nombala ukusuka mthubi ukukhanya elibomvu emnyama. Kubhaliwe afunyenwe emva Ucoco off icandelo nezwe intlaka of Conifers. Iipropati lwemichiza rosin (90% asidi resin, kuquka esisiseko - abietic) yenza ezingenakunyibilika emanzini kodwa enyibilikayo iEtere, utywala, chloroform kunye benzene. Xa lashushu 50-120 C. (ngokuba kwiintlobo ezahlukeneyo) imivalo rosin ziya zithambe.

Apho igama elithi "rosin"? Oku kusenokwenzeka zonakaliswa igama laloo mzi yamandulo yesiGrike isigcino, kuyo bakhula nemithi esinika into enjalo. Kumaxesha amandulo (iminyaka engaphezu kwamawaka amathathu eyadlulayo) ukusuka nentlaka turpentine elungiswe ngokushushubeza ngamasalela elomileyo yi rosin kweziyobisi kanye kwakudala.

Rosin - njengomncedisi, ngaphandle apho akunakwenzeka ukuba ukudlala, ezifana kunefidyoli, Purple, bass kabini, cello. Xa Hlikihla piece isaphetha weli kuvelisa molekyuli yamahala ukunika adhesion ethile ukuya umtya, ngaloo ndlela utsala isandi. rosin enjalo aphela rhoqo ukuvelisa ngendlela non-mveliso, intlaka eqokelelwe kuwa kuphela kongezwe bako "mfihlelo" azinayo ngamnye brand yabo (inokongezwa metal, isiliva okanye igolide, njalo njalo). Ukongeza, le rosin phambi atyabukile kweentende kwezemidlalo phambi kokuba, umzekelo, wrestlers kunye elilawulwa iinqwelo asukuba ekhwela kuzo phambi ngokutsiba.

Rosin - into eyayisetyenziswa kakhulu kwaye sifakwe kolu shishino. Kumaxesha angaphambili, oko imangalelwe isepha-ekwenziweni, ukuveliswa yokuncamathelisa, ngokulitywina ngumthwebeba. Namhlanje oololiwe kunye rosin esetyenziselwa ukulungisa Iityhubhu iglasi ukuqulunqa le chap ukuba nokuveliswa ivanishi, ushicilelo emsebenzini kumashishini brazing, kwakunye kwishishini ephepheni. Kwaye kuyo yonke indawo, usebenza iphambili - ukukwazi ukwenza iikhompawundi ezincangathi xa itshiswe.

kwimveliso rosin ngokubanzi ayitshintshanga phezu zeminyaka. izinto Ukuqalisa (kwizikhondo itha ziqokelelwe intlaka - oleoresin) sibekwe iityhubhu, apho ithathwa kunye ngomphunga okanye shushu ngomlilo. Ukusuka oleoresin quintal efunyenwe malunga 12 kg turpentine (Yek) ne-70 kg ye rosin, nto leyo kuphekwa ukususa fluid ibekwa kwizikhongozeli. Ukuba into licatshulwa isiphunzi, ukuba pre-emphefumlweni kwaye ngoko nomxube zeetships lwamanzi phantsi inkqubo gesi. Enye cubic meter iinkuni Unokuwuqhawula itha malunga kilograms amane rosin.

Zeziphi izixhobo ezingundoqo zolawulo zisetyenziswa ngamashishini ezivelisa rosin? № GOST 19113 - 84, ngokukodwa, iimfuno ezisisiseko eziliqela iimveliso kunye iparameters zemveliso. Ukusuka kuyo singafunda ukuba yintoni na kwesama rosin, yintoni na loxinano elamkelekileyo, isiqulatho amanzi, indawo ukuthambisa, inani acid, njl Uxwebhu nayo ibonisa ukuba iimfuno zokhuseleko senkqubo yemveliso (rosin -. Kuyinto abangaxhalabisiyo izinto eziyingozi, ekubeni kutshizwe wayo kunokubangela ukutyabuka), ukwamkelwa imithetho, iindlela uhlalutyo imithetho ezigqityiweyo imveliso, ukugcinwa kunye iwaranti.
