Qonda inkqubo ye-sand yokuqhuma kwesanti iqhelekileyo yokusebenza ngokuchanekileyo (ⅲ)

Uncedo loxinzelelo kunye nokomeleza komhlaba

Ngokubetha umphezulu womsebenzi nge-sand wit, uxinzelelo luyasuswa kwaye amandla omzimba anyuswe, njengonyango lomsebenzi we-springs, amabala e-Maching kunye nee-Springs.

I-Sand Blang Glaling Cage

Kukho imigangatho emiselweyo yamazwe aphesheya yococeko: Inye yeyona "ye-SSPC-" esekwe yi-United States ngo-1985; Okwesibini ngu "Sa-" owenziwe yiSweden ngonyaka wama-76, owahlulahlulwe ngokwamanqanaba amane, oyile SA1, SA3.5 no-SA3, kwaye ngumgangatho oqhelekileyo wehlabathi. Iinkcukacha zezi zilandelayo:

I-SA1-ilingana ne-USSPC-sp7. Usebenzisa iBrindush elula ye-Equery elula, indlela ye-Emery ye-Emery Grinding, ezi zezona iintlobo zezibini zokucoceka zisezantsi kakhulu, ukukhuselwa kwengcengcuko kungcono kakhulu kunenkqubo yokusebenza. Umgangatho wobugcisa wonyango lwe-SA1: Umphezulu we-ofisi yomsebenzi akufuneki ukuba i-oyile ebonakalayo, igrisi, i-oxide ye-oxide, i-rust, ipeyinti kunye nobunye ubumdaka kunye nobunye ubumdaka. I-SA1 ikwabizwa ngokuba kukucoca ibrashi. (okanye ukucoca iklasi)

Inqanaba le-SA2-ilingana ne-USSPC-nqanaba le-SP6. Ukusetyenziswa kwendlela yokucoca i-sandbiver, engezantsi kwisanti yonyango, oko kukuthi, iimfuno jikelele, kodwa ukukhuselwa kokudibana kwe-risayu ukuphucula uninzi. Umgangatho wobugcisa wonyango lwe-SA2: Umhlaba wokusebenza uya kukhululeka kwigrisi, ubumdaka, i-oxide, ipeyinti, i-rust, i-oxide, i-perrosion, kuquka amathunzi amancinci; Isixa esincinci sokwazina okuncinci okubangelwe ziziphene okanye kwi-rust; Ulusu olunesiphene kunye neziphene zepeyinti. Ukuba kukho i-dent kumphezulu wokuqala womsebenzi, i-rump encinci kunye nepeyinti iya kuhlala isezantsi kwe-dent. Ibanga le-SA2 likwabizwa ngokuba yiBanga lokuCoca iBakala (okanye iBakala lezoMveliso).

I-SA2.5-Eli linqanaba eliqhelekileyo elisetyenziswa kumzi-mveliso kwaye linokwamkelwa njengemfuno yobugcisa kunye nomgangatho. I-SA2.5 ikwabizwa kufutshane necocekile emhlophe (kufutshane nemhlophe okanye ngaphandle komhlophe). ISAHE2.5 UMGAQO-NKQUBO WOKUGQIBELA Isixa esincinci sokwazina okuncinci okubangelwe ziziphene okanye kwi-rust; Ulusu olunesiphene kunye neziphene zepeyinti.

Iklasi ye-SA3-ilingana ne-USSPC - i-SP5, yiklasi ephezulu yonyango kwishishini, ekwabizwa ngokuba yiklasi yokucoca imhlophe (okanye iklasi emhlophe). Inqanaba le-SA3 Inqanaba lobuGcisa boBugcisa: okufanayo nenqanaba le-SA2.5, kodwa isithunzi se-5%, iziphene, ukrokrela kwaye kufuneka kubekho.
