Black maloanlahla: etsa thepa thekenoloji

Black lehlohlojane hase kamehla ho e tala thepa tlhaho, ya hlahiswa ho tloha mafika ngollana 'mala ke ho sithabetsa le ho e lokisa e ileng ea latela. Ka linako tse ling ke particulate lintho tse bonahalang tse e tlotsitsoeng ka khethehileng sekontiri sebopeho kapa tarry. sebetsa sena ke ho hlokahala hore ho fumana sehlahisoa sa ka ho hanyetsa phahame abrasion le mamarello (litsobotsi life tse mamarello le o hlophisitsoeng tse ling thepa ea mohaho).

Mefuta le dikopo

Ho latela GOST ba batsho maloanlahla classified ke boholo karoloana:

1. From 5 ho ea ho 20 limilimithara - hlokoloa ha lehlohlojane (lehlohlojane), e emela sebopeho ho fetisisa e metle-grained.
2. From 20 ho 40 limilimithara - seaplane-grained lehlohlojane. Ka ho fetisisa e atisa ho sebelisoa ka ho haha.
3. From limilimithara 40 ho 70 - ka lintho tse bonahalang mahoashe, eo nakong ea tlhomamiso hangata a etsa rasklintsovka (Lejoe kabobotjha ho tlosa voids).
