HOW TO MAKE SOAP

HOW TO MAKE SOAP

Materials

  • Oil
  • water
  • sodium hydroxide

procedure

  • Pour  caustic soda into one of the fermenting tanks according to the required measurements. 
  • Stir very well and then cover tightly.
  • heat the oil adding the colorant. 
  • The heated oil should be removed from the heater and allowed to cool down. 
  • Pour the already heated oil into the mixing tank (tool), add the caustic soda solution and them mix thoroughly. 
  • At trace point, add the perfume and mix vigorously. 
  • Pour the mixture into the mould and allow to solidify
  • Cut, stamp and package the soap.

notice:

  1. The mixing tank is not made of aluminium because caustic soda may corrode it.
  2. pour caustic soda solution  into oil when they have about the same temperature (45-50 centigrade)
  3. Ratio of mixing oil 1:1, water 1/3, and caustic soda 1/7 please for more about the ration to mix, use soapcalc, or learn more about saponification index.
  4. Handle carefully caustic soda is corrosive. health safety is required

some other compounds may be used


  • soda ash ------------------- increase the quantity and quality of the product
  • sodium silicate------------- shining agent in soap production (it plays role of binding)
  • kaolin ----------------------- used as filler and extender
  • sodium sulphate / STPP ------used for strengthening fibres and gives strength to the soap
  • colorant
  • cucumber --------- soothe the skin, 
  • shea butter ------  superfatting oil 
  • monopotassium phosphate --------- hard water softener
  • beeswax --------- add hardness to soap

GUKORA ISABUNE MU BURYO BUBYARA INYUNGU

Ese byashoboka ko isabune yakorwa mu buryo bwunguka? iki ni ikibazo gikunze kwibazwa n'abatari bake cyane abamaze kumenya gukora isabune. Iyo igisubizo kibaye yego basubiza ko bidashoboka kubera ikiguzi cy'ibikenerwa (raw materials). Ariko iyo urebye neza ubona ahanini ikizamura ikiguzi cy'isabune ari impamvu yuko amavuta ahenze. Mu kureba icyakorwa kugira ngo gukora isabune bihinduke umushinga wunguka twafashe bumwe mu buryo bwifashishwa bigafasha uyikora kunguka, aho hongerwamo ibyongera ubwinshi n'ubunini bw'isabune(fillers/charges). Mu byongera ubwinshi bw'isabune turavuga ku ishwagara (whiting ari yo calcium carbonate). Iyo igiye kugurwa uyisaba yitwa wayitingi (whiting) yo mu isabune ikomeye igakoresha iri hagati ya 30% kugeza 50% by'amavuta arakoreshwa. Tugiye kubireba dufata urugero rwakwifashishwa. Reka turebe ibikenewe amavuta                         ...

GUTURAGA AMAGI UKORESHEJE THERMOSTAT

  UKO WATURAGA AMAGI Y'INKOKO ITANGIRIRO Gutaraga amagi bikorwa n'inkoko kugirango havemo imishwi ariko bishobora gukorwa n'abantu mu buryo butandukanye bita kubushyuhe bukwiye n'ubuhehere bakibuka guhindura igi buri nyuma y'amasaha nibura umunani. Muri ubwo buryo harimo gukoresha amashyanyarazi hifashijwe thermostat cyangwa arduino, no gukoresha ubushyuhe butangwa n'amatara  akoresha petroli (kerozene) azwi nka lanterne cyanwa se iyindi nkomoko y'ubushyuhe. ubwo buryo bwose bukenera ahava inkomoko  y'ubuherere ariyo  mazi. Iyo ubwo buryo bunogejwe hakorwamo imashini zituraga amagi.  uburyo turibandaho ni uburyo bukoresha amashanyarazi na thermostat n'amatara.   IBYO UKWIYE GUKORA UGIYE GUTURAGA AMAGI kureba amagi y'inkoko ibana n'isake kuyafata nibura mbere y'iminsi irindwi kubikaneza amagi araza gukoreshwa (igi ribikwa kandi rikarambikwa umutwe (agatwe gato) werekeje hasi naho igihade kinini gisa nikireba hejuru.

UKO WAKORESHE ARDUINO UNO MU GUTURAGA AMAGI

Mu guturaga amagi nkuko bisanzwe hagomba kuboneka ubushyuhe, ubuhehere ndetse amagi akanabirindurwa nibura gatatu ku munsi. Rero mu rwego rwo kugenzura ububushyuhe hashobora kwifashisha uburyo butandukanye. Muri  ubwo buryo bwo kugenzura ubushyuhe twavuga nka thermostat, gukoresha thermometre no gukoresha arduino(microcontrollers).  Uburyo  buravugwaho ni ubwo gukoresha microcontroller ya arduino.   Turabona: Kumenya Arduino ARDUINO UNO BOARD IDE UKO WASHYIRA ARDUINO MURI MUDASOBWA GUKORA GAHUNDA YA ARDUINO Ibindi bikenerwa SENSOR YUMVA UBUSHYUHE N'UBUHEHERE RELAY POWER SUPPLY ITARA CIRCUIT Kode wakoresha Ibyo guturaga amagi KUMENYA ARDUINO Arduino ni urubuga rw'isoko y'ubumenyi ifunguye kuri buri wese ikaba kompani itanga igice gifatika kiriho agace kafatwa nk'umutima cg ubwonko (microcontroller) kongerwamo gahunda za mudasobwa (code) kug...
