Dry ice blasting machine cleans with dry ice pellets shocking and swashing the dirt by the high speed. The solid dry ice pellets become gas state during the shock blasting. The dry ice pellets expand nearly 800 times in less than 0.001 seconds. Finally, the dry ice pellets sublimate and there aren’t any pollutants except dirt removed after dry ice cleaning. About dry ice blasting, many people still have doubts in many aspects, so our Shuliy machinery summarized some FAQs here for you, wish you have a better understanding both of the dry ice blasting and the dry ice blasting machine.
Q: What is Dry Ice Blasting?
A: Dry Ice Blasting is a new type of cleaning method with the advantages of non-abrasive, non-flammable and non-conductive, which is absolutely environment-friendly and can be widely used in many fields. The dry ice cleaning process should use the dry ice pellets which is usually with the diameter less than 3mm or use the dry ice blocks. Unlike other types of cleaning methods, dry ice blasting leaves no secondary waste to be cleaned up and does not utilize water or chemicals in the cleaning process.
Q: How does the dry ice blasting machine work?
J: Kabla ya kutumia mashine kavu ya kulipua barafu, tunapaswa kuweka pellets kavu za barafu kwenye chombo cha mashine kavu ya kulipua barafu kwanza. Kisha hose ya mlipuko wa barafu kavu itapiga pellets kavu ya barafu kwenye uso wa kitu kwa kasi ya juu, na uchafu utapasuka haraka na compact ya pellets kavu ya barafu. Hatimaye, usablimishaji wa barafu kavu unapofanyika, hupanuka kwa ujazo wa 800%, na kusukuma uchafu kutoka kwenye uso.
Q: Will dry ice blasting damage the surface being cleaned?
J: Kwa juhudi zetu kubwa za kuendelea kutafiti na kusoma kuhusu ukavu wa ukavu wa barafu, teknolojia yetu ya kusafisha barafu kavu imerekebishwa na kuboreshwa ili iweze kusafisha sehemu nyeti na korofi. Hizi huanzia kusafisha bodi za mzunguko hadi kusafisha slag ya weld, bila kuharibu uso.
Q: Can dry ice blasting clean online high temperature equipment?
J: Usafishaji wa barafu kavu unafaa zaidi kwa kusafisha vifaa vya mtandaoni vya halijoto ya juu. Viwango vingi vya uchafuzi huwa chini kwa joto la juu kuliko halijoto iliyoko, kwa hivyo kusafisha barafu kavu ni chaguo nzuri. Kwenye vifaa vingine, kusafisha kwa joto la juu kunaweza kuwa mara 3-5 kwa kasi zaidi kuliko kusafisha kwenye joto la kawaida. Zaidi ya hayo, baada ya usafishaji wa mwisho wa barafu, barafu kavu huingizwa kwenye angahewa, kwa hivyo hakuna mabaki ya kusafisha yanayoachwa kwenye kifaa.
Q: What is the amount of dry ice used in dry ice blasting?
J: Kulingana na uzoefu wetu, utokaji wa barafu yetu kavu kwa ujumla hurekebishwa hadi takriban kilo 0.5 ~ 1.5 kwa dakika wakati wa mchakato wa kusafisha, lakini kutakuwa na mapumziko na vipindi wakati wa mchakato kavu wa ulipuaji wa barafu. Tunahesabu utokaji wa barafu kavu wa kilo 1 kwa dakika na wakati wa kusitisha kusafisha kwa 50%. Kisha, matumizi ya barafu kavu kwa saa moja ni karibu kilo 30.
Q: Can dry ice blasting remove paint?
A: Yes, of course, the dry ice blasting can remove the paint. Dry ice blasting is aggressive enough to remove the paint but delicate enough to protect your investment. Cleaning with dry ice can clean grime, remove lead-based paint, and bring out original detail. Unlike abrasive or chemical restoration methods, dry ice blasting does not scratch or stain the surface. Instead, it uncovers the underlying surface and restores a structure to its original state. Dry ice blasting is easy to control and reaches the tightest cracks and corners without damaging surrounding objects.
