10. Fetola boemo - e sebediswa ho lokisa boemo ba lebone la Bunsen le paterone
Boemo a: sampole e beoa maemong a tloaelehileng a sepakapaka a boletsoeng ho gb6529, ebe sampole e kenngoa ka setshelong se koetsoeng.
Boemo ba B: beha sampole ka ontong ka (105 ± 3) ℃ ka metsotso e (30 ± 2), e ntše, 'me u e behe ka har'a mochini o omisang bakeng sa ho e pholisa. Nako ea ho pholisa ha ea lokela ho ba ka tlase ho metsotso e 30.
Liphetho tsa boemo a le boemo B ha li bapisoe.
Lokisa sampole ho latela maemo a ho futhumatsa mongobo a boletsoeng likarolong tse ka holimo:
Boemo a: boholo ke 300 mm * 89 mm, disampole tse 5 di nkuwa ho tloha lehlakoreng la longitude (longitudinal) mme dikotwana tse 5 di nkuwa ho tloha lehlakoreng la latitude (transverse), ka kakaretso ya disampole tse 10.
Boemo ba B: boholo ke 300 mm * 89 mm, disampole tse 3 di nkuwa ka lehlakoreng la longitude (longitudinal), mme dikotwana tse 2 di nkuwa ka lehlakoreng la latitude (transverse), ka kakaretso ya disampole tse 5.
Sebaka sa ho etsa disampole: seha sampole bonyane 100 mm hole le lehlakore la lesela, mme mahlakore a mabedi a sampole a bapile le ditataiso tsa lesela tse kobehileng (longitudinal) le tse kobehileng (transverse), mme bokahodimo ba sampole bo tla hloka tshilafatso le matheba. Sampole e kobehileng e ke ke ya nkuwa khoeleng e le nngwe e kobehileng, mme sampole ya weft e ke ke ya nkuwa khoeleng e le nngwe e kobehileng. Haeba sehlahiswa se tla lekwa, sampole e ka ba le dithupa kapa mekgabiso.
1. Lokisa sampole ho latela mehato e kaholimo, tiisa paterone sekotwaneng sa paterone ea masela, boloka sampole e bataletse kamoo ho ka khonehang, ebe u fanyeha paterone thupeng e leketlileng ka lebokoseng.
2. Kwala lemati le ka pele la kamore ea teko, tobetsa khase ho bula valve ea phepelo ea khase, tobetsa konopo ea ho hotetsa ho bonesa lebone la Bunsen, 'me u lokise phallo ea khase le bophahamo ba lelakabe ho etsa hore lelakabe le tsitse ho (40 ± 2) mm. Pele ho teko ea pele, lelakabe le lokela ho chesoa ka mokhoa o tsitsitseng boemong bona bonyane motsotso o le mong, ebe u tobetsa konopo ea ho tima khase ho tima lelakabe.
3. Tobetsa konopo ea ho hotetsa ho bonesa setofo sa Bunsen, lokisa phallo ea khase le bophahamo ba lelakabe ho etsa hore lelakabe le tsitse ho (40 ± 2) mm. Tobetsa konopo ea ho qala, lebone la Bunsen le tla kena ka bohona boemong ba paterone, 'me le tla khutla ka bohona ka mor'a hore lelakabe le sebelisoe nakong e behiloeng. Nako ea hore lelakabe le sebelisoe sampole, ke hore nako ea ho hotetsa, e khethoa ho latela maemo a khethiloeng a taolo ea mongobo (sheba Khaolo ea 4). Boemo a ke 12s 'me boemo ba B ke 3S.
4. Ha lebone la Bunsen le kgutla, T1 e kena ka bohona boemong ba nako.
5. Ha lelakabe le hodima paterone le tima, tobetsa konopo ya nako, T1 e emisa nako, T2 e qala nako ka bohona.
6. Ha mosi o fela, tobetsa konopo ea nako 'me T2 e emisa nako
7. Etsa Mekhoa e 5 ka ho latellana. Sistimi e tla tsoa ka bo eona ho sebopeho sa polokelo, e khethe sebaka sa lebitso, e kenye lebitso ho le boloka, ebe e tobetsa boloka
8. Bula libaka tsa ho ntša mosi ka laboratoring ho ntša mosi o tsoang ka har'a khase e hlahisoang tekong.
9. Bula lebokose la teko, ntsha sampole, mena mola o otlolohileng ntlheng e phahameng ka ho fetisisa ea sebaka se senyehileng ho latela bolelele ba sampole, ebe o leketlisa hamore e boima e khethiloeng (eo u e fileng eona) lehlakoreng le ka tlase la sampole, hoo e ka bang 6 mm hole le tlase le mathoko a eona, ebe o phahamisa butle lehlakore le leng la pheletso e ka tlase ea sampole ka letsoho, tlohela hamore e boima e leketlile moeeng, ebe o e beha fatše, lekanya le ho ngola bolelele ba ho taboha ha sampole le bolelele ba tšenyo, bo nepahetseng ho 1 mm. Joalokaha ho bontšitsoe setšoantšong se ka tlase, bakeng sa sampole e kopantsoeng le ho hokahanngoa hammoho nakong ea ho tuka, ntlha e phahameng ka ho fetisisa ea ho qhibiliha e tla ba teng ha ho lekanngoa bolelele bo senyehileng.
Tekanyo ea bolelele ba tšenyo
10. Tlosa lithōle ka kamoreng pele u leka sampole e latelang.
Ho ya ka maemo a taolo ya mongobo Kgaolong ya 3, diphetho tsa dipalo ke tse latelang:
Boemo a: boleng bo tloaelehileng ba nako ea ho chesa, nako ea ho chesa le bolelele bo senyehileng ba mehlala e 5 e potlakileng ka tatellano ea longitude (longitudinal) le latitude (transverse) li baloa ka ho latellana, 'me liphetho li nepahetse ho 0.1s le 1mm.
Boemo ba B: boleng bo tloaelehileng ba nako ea ho chesa, nako ea ho chesa le bolelele bo senyehileng ba mehlala e 5 boa baloa, 'me liphetho li nepahetse ho 0.1s le 1mm.
